What is the bandwidth? (10 points) Twenty-four voice signals are to be multiplexed and transmitted over twisted pair. What is the bandwidth required (in bps) if synchronous time division multiplexing is used, if we use the standard analog to digital sampling rate, and if each sample is converted into an 8-bit value? (Suppose, each voice channel has a bandwidth of 4000 Hz).
