Question
[Q2] n analog signals (each is bandlimited to 10kHz) are transmitted simultaneously over a channel via
the TDM-PAM system. If the TDM output transmission pulse rate is set to be 360k samples per second,
compute n. (Assume the sampling frequency is the Nyquist rate).
[Q3] Let m(t) be a baseband signal whose spectrum is described in the figure below. This signal is sampled
at the rates (a) 17kHz, (b) 30% over the Nyquist rate. Draw the spectrum of the sampled signal in each
case.
