An analog signal of the form is bandlimited to the range 900 ≤ F ≤ 1100 Hz. It is used as an input to the system shown in Fig. P10.25.

(a) Determine and sketch the spectra for the signals x(n) and ω(n).

(b) Use a Hamming window of length M = 31 to design a lowpass linear phase FIR filter H(ω) that passes {a(n)}.

(c) Determine the sampling rate of the A/D converter that would allow us to eliminate the frequency conversion in Fig. P10.25.
