*The following links are to the best KiCAD Tutorials that I've found. They're the only ones with voice narration. Unfortunately, the video's creator thought it would be better to use a synthesized voice. It can be quite tiresome. (Posted by Chris Lau 4/9/12)

*I enjoyed the Tutorials 1 and 2 that Chris put on the page it is very good at specifying the basics. (Matthew Blaire 4/10/12)
**I also Have found a helpful tutorial on creating components [http://www.youtube.com/watch?v=xOHGv8pQDSg&feature=relmfu Add Component Tutorial]

==Homework #11==

===Matthew Blaire===

*I researched the ability to cross platforms and found that the only way to do this is to copy the net list of the schematic. You can do this by opening the files in the viewer and copying the created net list to another spice program.

*While the net list is not perfect and still requires some modifying, for the most part between spice programs the net list is compatible.

*I checked this not only with the programs and a couple hours of online research, but also through my Dad, who is an electrical engineer and has worked extensively with both programs.

==Homework #11==

===Matthew Blaire===

*I researched the ability to cross platforms and found that the only way to do this is to copy the net list of the schematic. You can do this by opening the files in the viewer and copying the created net list to another spice program.

*While the net list is not perfect and still requires some modifying, for the most part between spice programs the net list is compatible.

*I checked this not only with the programs and a couple hours of online research, but also through my Dad, who is an electrical engineer and has worked extensively with both programs.

'''LTspice Mixer Analysis:'''
What I basically did was I took the basic differential amplifier design and tested
the inputs with the two different designs: one with the data coming in through the
top transistor, and one where the data comes in through the bottom input. The pdf
diagramming the setups are displayed below.

The following is a schematic with the data coming in the top Transistor.
[[File:limit_on_top.gif|center|alt=A schematic]]
The following is the simulation of the data.
[[File:limit_on_top_graph.gif|center|alt=A graph]]
You can see that some of the data is limited by the bottom resistor so this is not
as good as the other way of which the simulation is done below.
[[File:limit_on_bottom_circ.gif|center|alt=A schematic]]
This is the Graph of the simulation, you can see that the data is passed in a better
range and that the wave form of the slower wave data is taken from the faster data.
[[File:limit_on_bottom.gif|center|alt=A graph]]
There is still some distortion at the bottom of the graph but overall I think this passes better
data than putting the oscillator on the top. If the transistors were biased
better, I think that the data would show a little better.

This is the Graph of the simulation, you can see that the data is passed in a better
range and that the wave form of the slower wave data is taken from the faster data.

There is still some distortion at the bottom of the graph but overall I think this passes better
data than putting the oscillator on the top. If the transistors were biased
better, I think that the data would show a little better.

What I basically did was I took the basic differential amplifier design and tested
the inputs with the two different designs: one with the data coming in through the
top transistor, and one where the data comes in through the bottom input. The pdf
diagramming the setups are displayed below.

The following is a schematic with the data coming in the top Transistor.

The following is the simulation of the data.
[[File:limit_on_top_graph.gif|center|alt=A graph]]
You can see that some of the data is limited by the bottom resistor so this is not
as good as the other way of which the simulation is done below.
