2. From Lathi's text (Ch. 6, Delta Modulation) 6.7-1 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 E to avoid slope overload. (b) Determine the granular noise power No if the voice signal bandwidth is 3.4 kHz. (c) Assuming that the voice signal is sinusoidal, determine the output signal/power So 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. Note: To solve this problem, please take a look at the note attached at the end.
