In a single-integration DM system, the voice signal is sampled at a rate of 64 kHz, similar to PCM. The maximum signal amplitude is normalized as Amax = 1. (a) Determine the minimum value of the step size o to avoid slope overload. (b) Determine the granular noise power N, if the voice signal bandwidth is 3.4 kHz. (c) Assuming that the voice signal is sinusoidal, determine S, and the SNR. (d) Assuming that the voice signal amplitude is uniformly distributed in the range (-1, 1), determine So and the SNR. (e) Determine the minimum transmission bandwidth. In a single-integration DM system, the voice signal is sampled at a rate of 64 kHz, similar to PCM.
