Question: In Figure, x[n] = x c (nT) and y[n] = x[2n]. (a) Assume that x c (t) has a Fourier transform such that X c

In Figure, x[n] = xc(nT) and y[n] = x[2n].

(a) Assume that xc(t) has a Fourier transform such that Xc(j?) = 0, |?| > 2? (100). What value of T is required so that?

X(ej?) = 0, ? ? ? ??/2

(b) How should T? be chosen so that yc(t) = xc(t)?
