HW #1 - Make a personal page on this wiki (Chris Lau)(Jodi S. Hodge)(Chris Wills)
HW #2 - Write a tutorial about installing and/or using Octave (Chris Lau)(Jodi S. Hodge)(Victor Shepherd)
HW #3 - Show graphically that $\int_{- \infty}^{\infty} e^{j 2 π f (t - u)} d f = δ (t - u)$ (Chris Lau)(Jodi S. Hodge)(Chris Wills)(Victor Shepherd)

HW #4 - Given a linear time-invariant system where $u (t)$ produces an output $w (t)$ , find the output due to any function $x (t)$ (Chris Lau)
HW #5: (Chris Lau)
- Part 1 - Find $ℱ [e^{- σ t} x (t) u (t)]$ and relate it to the Laplace Transform. Derive the Inverse Laplace Transform of this from the inverse Fourier Transform.
- Part 2 -

HW #6 - Pick a property of the Fourier Transform & present it on the Wiki. Make a table with all your properties. Interpret your property. (Ben Henry)(Chris Lau)
HW #7 - Finish the practice tests
HW #8 - Make a page about interpolating FIR filters. Note how many multiply/add operations.(Jodi S. Hodge)
HW #9 - Add to #8 writeup how to do a decimating filter and figure out how many multiply & adds are needed for a n/2 decimating low pass filter.(Jodi S. Hodge)
HW #10 - Use Octave (or Mathlab or Silab) to plot the frequency response of low pass filters with cut off frequencies of 1/32T, 1/8T, and 1/4T and compare how many coeffficients are needed with an eye to answer the question "Is it less calculation to decimate and then filter, or better to put the filter in the pre-decimation filter?" (Jodi S. Hodge)
HW #11 - Is our method the same as Mark Flower's? See Wiki.(Same # multiply and adds? Notes 11/3/10) (Jodi S. Hodge)
