Question

Fig. 1.35 shows the block diagram of a certain DSP system, given the fs is the sampling frequency used and

X(t) = cos (2000πt) + 2cos (4000πt) + 3cos (10000 πt)

If fc = 4kHz and fs = 8kHz, sketch the spectrum of the signal y(t) for 0 ≤ f ≤ 8kHz. Briefly point out the possible problems or limitations for processing x(t), if any.
