An analog signal xa(t) is bandlimited to the range 900 = F = 1100 Hz. It is used as an input to the system shown in figure. In this system, H(?) is an ideal lowpass filter with cutoff frequency Fc = 125Hz.

(a) Determine and sketch the spectra for the signals x(n), ?(n), v(n), and y(n).

(b) Show that it is possible to obtain y(n) by sampling xa(t) with period T = 4 milliseconds.
