1. The continuous-time signal x(t) has the Fourier transform Xc(j) shown below. x(jn) 40π = With sampling period T, the sampled discrete time signal is x[n] = (nT). Let x,(t) [n](t-nT). x[n] and x,(t) have Fourier transform X(eu) and X,(j), respectively. Please sketch X(eu) and X,(j) for the following values of T. (a) T = 0.02. (b) T = 0.025. (c) T = 0.03.
