5.2-10 For a PCM signal, determine the minimum necessary L if the compression parameter is μ = 100 and the minimum SNR required is 42 dB. Recall that L = 2" is required for a binary PCM. Determine the output SNR for this value of L. 5.2-11 Five sensor output signals, each of bandwidth 240 Hz, are to be transmitted simultaneously by binary PCM. The signals must be sampled at least 20% above the Nyquist rate. Framing and synchronizing requires an additional 0.5% extra bits. The PCM encoder of Prob. 5.2-10 is used to convert these signals before they are time-multiplexed into a single data stream. Determine the minimum possible data rate (bits per second) that must be transmitted, and the minimum bandwidth required to transmit the multiplex signal.
