1. Consider a sequence x[n] obtained by sampling a continuous-time signal x[n] = xc(nT) and xc(t) = 5 + 10 cos(80π t) - 10 sin(50π t). (a) Plot the magnitude and phase spectra of Xc(jΩ). (b) Plot the magnitude spectra of X(e^jω) = (1)/(T)∑k=-∞^∞ Xc ( j(ω)/(T) - j(2π k)/(T)) when T = 0.01. (c) Do the same problem in part (b) except T = 0.02? (d) What is the maximum sampling frequency fs so that the frequency aliasing can be avoided?
