Q9) A digital communication system transmits signals with a maximum frequency of 10 kHz and a minimum frequency of 1 kHz. The system samples the signals at a rate of 20,000 samples per second. What is the minimum number of bits per sample that the system must use in order to accurately reproduce the original signals? A. I bit/sample B. 2 bits/sample C. 3 bits/sample D. 4 bits/sample 210) A pulse width modulation (PWM) system uses a carrier frequency of 1 kHz and encodes Is and Os by varying the width of the pulses between two values, W1 and W2. If the width of the pulses is varied continuously, what is the maximum data rate (in bps) that the system can support? A. 500 bps B. 1,000 bps C. 2,000 bps
