Question:

Consider the sequence x[n] Whose Fourier transform X(e^j?) is shown in Figure,?

and?

x_d[n] = x_s[Mn] = x[Mn]

(a) Sketch X_s(e^j?) and X_d(^?j?) for each of the following cases:

(i) M = 3, ?_H = ? / 2

(ii) M = 3, ?_H = ? / 4

(b) What is the maximum value of ?_H that will avoid aliasing when M = 3?
