To use the FFT for convolution, you need to do it in blocks, which leads to end effects, and more latency, but if your blocks are big enough, it speeds up the convolution.

*The truncated Fourier series or DFT method of FIR filter design gives the best approximation of the desired frequency response in a least squared error sense, but it is not very good near discontinuities. [http://itee.uq.edu.au/~elec4600/elec4600_lectures/1perpage/lectremez.pdf The Parks-McClellan] (Remez) iterative algorithm gives equal ripple in the pass band and stop band. This is the best in terms of minimizing the maximum error in each area, which is usually better in the real world. MATLAB/octave have automated functions to do that.

===Math Editors for Your Notebook===
You can make your notebook here on the wiki, but there are other options, including things like writing you notes on paper and using photo processing software to make notes like the [http://people.wallawalla.edu/~Rob.Frohne/ClassNotes/engr455index.htm old class notes]. You can also make screencasts or videos for your notebook.
*[https://jupyterlab.readthedocs.io/en/stable/ JupyterLab:] This is my current favorite for making notebooks with a "literate programming" approach. It allows you to mix prose and other things with your equations in LaTex or python or octave code that illustrate the concepts.
*LaTex: I suggest opening opening the following [http://www.math.duke.edu/computing/tex/templates/samplefile.tex sample file] with any of the LaTex editors below. LaTex is a document processing language that you compile like C or other compiled languages. It does produce the nicest looking documents, but it takes a bit of expertise to do that. If you are bound for graduate school, it is well worth learning.
**[http://www.texstudio.org/ TexStudio] works with Windows, Linux, and OS X, has a previewer, menus to help newbies, and is about the most featured LaTex editor I have tried.
**[http://www.xm1math.net/texmaker/ Texmaker] is a LaTex editor with preview and a bunch of menus that help to figure out what you need to type to get the effects you want. It works on Linux, Windows, and OS X.
**[https://en.wikipedia.org/wiki/Gummi_(software) Gummi] is a LaTex editor with preview for Linux and Windows.
**[https://www.codecogs.com/latex/eqneditor.php Online LaTeX Editor] especially for equations. This is useful for other systems that take LaTex input when you don't know LaTex yet.
*[http://lurchmath.org/ Lurch] is a math editor for your desktop that will check your logic. For this class it is primarily useful as an easy editor for mathematical subjects.
*[https://andrejv.github.io/wxmaxima/index.html wxMaxima] is a document based GUI for the Maxima computer algebra system. You can do quite a bit of algebra and calculus in wxMaxima. The notebooks it produces look good, but not as good as LaTex documents, however, you can easily change them, and it will redo all the math with the changes. I found a [https://bugs.launchpad.net/ubuntu/+source/wxmaxima/+bug/1311770 bug] in the version that come with Ubuntu 15.04 where it segfaults when you type in a parenthesis to one of the helpful windows that come up when using the menus. I solved it by using the [https://launchpad.net/~peterpall/+archive/ubuntu/wxmaxima-nightlies nightly builds] from Peter Pall. As with most of the tools here, it will [http://www.matrix44.net/blog/?p=1029 integrate in with LaTex].
*[http://www.sagemath.org/ SageMath] is a computer algebra system similar to wxMaxima that uses python, maxima and other tools to make a very nice and powerful tool for making a notebook. In order to make it work with the octave kernel, I had to use the latest version, which I obtained at [https://help.ubuntu.com/community/SAGE the Ubuntu Sage wiki] where I the instructions to install the upstream binary like this:
sudo apt-add-repository -y ppa:aims/sagemath
sudo apt-get update
sudo apt-get install sagemath-upstream-binary
*[https://cloud.sagemath.com SageMath on the cloud] uses sage (a computer algebra system) and latex to make your document. It has a nice preview that shows you what you get with your LaTex code. It also has a Linux terminal that you can use for octave and other things. You can create all kinds of files. It works well with the online LaTex editor below.
**[http://www.sagemath.org/help-video.html Some SageMath Videos] I found the two Introduction videos very useful.
*[http://www.ptc.com/engineering-math-software/mathcad?ab_eid=491&ab_vid=94189&gclid=CjwKEAjw1f6vBRC7tLqO_aih5WISJAAE0CYwihsuWeadsqwBL38_IQofPffXZUCfFMmau725f_zk-BoCbkrw_wcB PTC Mathcad] works for Windows and costs something, but is available on the campus network.
*LibreOffice is an open source word processor.
*Microsoft Word is a fancy word processor that I think you can get for free or minimal cost when you are a WWU student.
*[https://www.maplesoft.com Maple] is a commercial symbolic mathematics package similar to maxima. It will do notebooks. It is available on the school network.
*[https://www.wolfram.com/mathematica/ Mathematica] is another commercial symbolic software package. I don't think it is available on the school network.
*[https://www-fourier.ujf-grenoble.fr/~parisse/giac.html Xcas is my current favorite open source alternative to Maple or Mathematica.] Xcas uses syntax compatible with the TI-89, or Maple, or muPad, or the TI NSpire CAS or Voyager 200. It runs on Windows, Linux, or OS X and is also available on Android for your phone, and I use it that way sometimes too. It is based on Giac which was chosen for the recent fancy HP CAS calculator, and for [https://www.geogebra.org/ Geogebra].

To use the FFT for convolution, you need to do it in blocks, which leads to end effects, and more latency, but if your blocks are big enough, it speeds up the convolution.

===Math Editors for Your Notebook===
You can make your notebook here on the wiki, but there are other options, including things like writing you notes on paper and using photo processing software to make notes like the [http://people.wallawalla.edu/~Rob.Frohne/ClassNotes/engr455index.htm old class notes]. You can also make screencasts or videos for your notebook.
*[https://jupyterlab.readthedocs.io/en/stable/ JupyterLab:] This is my current favorite for making notebooks with a "literate programming" approach. It allows you to mix prose and other things with your equations in LaTex or python or octave code that illustrate the concepts.
*LaTex: I suggest opening opening the following [http://www.math.duke.edu/computing/tex/templates/samplefile.tex sample file] with any of the LaTex editors below. LaTex is a document processing language that you compile like C or other compiled languages. It does produce the nicest looking documents, but it takes a bit of expertise to do that. If you are bound for graduate school, it is well worth learning.
**[http://www.texstudio.org/ TexStudio] works with Windows, Linux, and OS X, has a previewer, menus to help newbies, and is about the most featured LaTex editor I have tried.
**[http://www.xm1math.net/texmaker/ Texmaker] is a LaTex editor with preview and a bunch of menus that help to figure out what you need to type to get the effects you want. It works on Linux, Windows, and OS X.
**[https://en.wikipedia.org/wiki/Gummi_(software) Gummi] is a LaTex editor with preview for Linux and Windows.
**[https://www.codecogs.com/latex/eqneditor.php Online LaTeX Editor] especially for equations. This is useful for other systems that take LaTex input when you don't know LaTex yet.
*[http://lurchmath.org/ Lurch] is a math editor for your desktop that will check your logic. For this class it is primarily useful as an easy editor for mathematical subjects.
*[https://andrejv.github.io/wxmaxima/index.html wxMaxima] is a document based GUI for the Maxima computer algebra system. You can do quite a bit of algebra and calculus in wxMaxima. The notebooks it produces look good, but not as good as LaTex documents, however, you can easily change them, and it will redo all the math with the changes. I found a [https://bugs.launchpad.net/ubuntu/+source/wxmaxima/+bug/1311770 bug] in the version that come with Ubuntu 15.04 where it segfaults when you type in a parenthesis to one of the helpful windows that come up when using the menus. I solved it by using the [https://launchpad.net/~peterpall/+archive/ubuntu/wxmaxima-nightlies nightly builds] from Peter Pall. As with most of the tools here, it will [http://www.matrix44.net/blog/?p=1029 integrate in with LaTex].
*[http://www.sagemath.org/ SageMath] is a computer algebra system similar to wxMaxima that uses python, maxima and other tools to make a very nice and powerful tool for making a notebook. In order to make it work with the octave kernel, I had to use the latest version, which I obtained at [https://help.ubuntu.com/community/SAGE the Ubuntu Sage wiki] where I the instructions to install the upstream binary like this:
sudo apt-add-repository -y ppa:aims/sagemath
sudo apt-get update
sudo apt-get install sagemath-upstream-binary
*[https://cloud.sagemath.com SageMath on the cloud] uses sage (a computer algebra system) and latex to make your document. It has a nice preview that shows you what you get with your LaTex code. It also has a Linux terminal that you can use for octave and other things. You can create all kinds of files. It works well with the online LaTex editor below.
**[http://www.sagemath.org/help-video.html Some SageMath Videos] I found the two Introduction videos very useful.
*[http://www.ptc.com/engineering-math-software/mathcad?ab_eid=491&ab_vid=94189&gclid=CjwKEAjw1f6vBRC7tLqO_aih5WISJAAE0CYwihsuWeadsqwBL38_IQofPffXZUCfFMmau725f_zk-BoCbkrw_wcB PTC Mathcad] works for Windows and costs something, but is available on the campus network.
*LibreOffice is an open source word processor.
*Microsoft Word is a fancy word processor that I think you can get for free or minimal cost when you are a WWU student.
*[https://www.maplesoft.com Maple] is a commercial symbolic mathematics package similar to maxima. It will do notebooks. It is available on the school network.
*[https://www.wolfram.com/mathematica/ Mathematica] is another commercial symbolic software package. I don't think it is available on the school network.
*[https://www-fourier.ujf-grenoble.fr/~parisse/giac.html Xcas is my current favorite open source alternative to Maple or Mathematica.] Xcas uses syntax compatible with the TI-89, or Maple, or muPad, or the TI NSpire CAS or Voyager 200. It runs on Windows, Linux, or OS X and is also available on Android for your phone, and I use it that way sometimes too. It is based on Giac which was chosen for the recent fancy HP CAS calculator, and for [https://www.geogebra.org/ Geogebra].

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

* Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
* Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
*[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
**[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
**[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
**[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

The effective series resistance and temperature behavior are much better though.
**[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

The effective series resistance and temperature behavior are much better though.
**[http://beamdream.solarbotics.net/Tutorials/CapGuide.htm The markings] on capacitors are often based on pF. There will be three digits, like 104 for 0.1uF. The first two digits are the digits of the value, and the next number is the number of zeros to add after that to denote the capacitance in pF. Thus 104 in 10 * 1e4 pF.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.

** Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
** Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.
