Determine whether the systemnoise, Electrical Engineering

Assignment Help:

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.
