The expression given in Problem for (S0/N0)PCM is plotted for a sinusoidal message in Figure to show the performance curves for a PCM system using a polar waveform.
(a) Comment on the threshold effect.
(b) For the polar system of Problem, with Nb = 8 and ( Si /Ni )PCM = 32, determine whether the systemnoise has signi?cant effect on performance.
