Delta Modulation & Demodulation: Theory & Applications

SOLVED: PROBLEM 3. (Delta Modulation) Consider a delta modulation (DM) system used to transmit a voice signal, which is uniformly sampled at the rate of 64 kHz. Assume the following specifications: Voice signal bandwidth = 4 kHz, Maximum signal amplitude = 10 volts.(a) To avoid slope overload distortion, what is the minimum permissible value of the step size used in the system? (5 pts)(b) Determine the average power of granular noise. Assume the noise is uniformly distributed. (5 pts)(c) Determi

SOLVED: In normal operation, a delta modulation ( DM ) transmission link system samples the input message signal at 6 times its maximum frequency. In this case when the message signal bandwidth is 3 kHz , the quantization step size is 250 milli volts. If the input message signal's bandwith is lowered to 1 kHz, determine its maximum amplitude permissible such that slope overload does not occur
