(a) Consider a PCM system in which 30 channels are to be time division multiplexed. The bandwidth of each channel is 3 kHz . The sampling rate is $33.33 \%$ higher than the theoretical minimum and 8 bits are used for each sample. Determine the required bit rate and find the minimum required transmission bandwidth.
Explanation
The bit rate is calculated based on the sampling rate and the number of bits used for each sample. The minimum required transmission bandwidth is determined by the highest frequency component in the signal.
