Question:

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

and?

xd[n] = xs[Mn] = x[Mn]

(a) Sketch Xs(ej?) and Xd(?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?
