484 Assignment 5
1.1. Implement the squaring and cubing of a sine wave, and plot
the resulting time domain waveforms and spectra. Use a sampling
rate of 8 KHz and a sine wave at 1 KHz.
1.2. Repeat for a sine wave at 2.5 KHz, and observe the aliasing.
1.3 Repeat 1.2 with sufficient oversampling to eliminate the
Implement an example of overdrive, distortion and fuzz on a
unprocessed (more or less) guitar clip
(or find your own guitar
clip). Set the parameters to clearly distinguish between the 3
Implement an exciter using the flute2.wav file, and compare to
simply increasing the treble with a shelving filter.
Using the Toms Diner clip, create 5 stereo files with both L and R
channels of equal amplitude but different delays.
Prepare the 5
files with delays chosen so that the signal appears to come from 100%
Left, 50% left, Center, 50% Right, 100% Right. Specify the delays
used in each case. Repeat
with channels of equal delay but different amplitudes. Specify
the amplitudes in each case.
