Question

Let xa(t) be an analog signal with bandwidth B = 3 kHz. We wish to use a N = 2m- point DFT to compute the spectrum of the signal with a resolution less than or equal to 50 Hz. Determine

(a) the minimum sampling rate,

(b) the minimum number of required samples, and

(c) the minimum length of the analog signal record.
