- What frequency would you hear if you synthesized a sine wave at 88000 Hz.
at a sample rate of 44100?
- Draw a block diagram showing how to use thresholding to detect when one
audio signal exceeds another one in value. (You might want to do this to
detect and filter out feedback from speakers to microphones.)
- Using the techniques of section 3.7, draw a block diagram
for generating two phase-locked sinusoids at 500 and 700 Hz.
