A signal with a bandwidth of 750 Hz must be sampled.

a. What is the Nyquist rate of the signal?

b. What is the minimum sampling frequency needed to avoid aliasing?

c. Unbeknownst to us, the signal is contaminated with noise at a 15-kHz rate. What

happens to this noise when sampled at the frequency specified in part b?
