1. Delta modulation quantizes the difference between the present and the previous sample value with just two-levels and encodes it by using just a single bit. Illustrate the simple algorithm to implement delta modulation. Also critically analyze the problem encountered when the variations in adjacent samples of the analog signal are quite fast as compared to the step size

2. A digital transmission system transmits data at the data rate of 1 Mbps. (a) How many extra bits per second are received by the receiver if the receiver clock is 0.1% faster than the sender clock? (b) What happens if the data rate of sender is 1 kbps only?
