Twenty 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, along with the standard analog-to-digital sampling rate, and each sample is converted into an 8-bit value?
Please refer to http://en.wikipedia.org/wiki/Sampling_rate for more information on common voice sampling rates in use. This response considers standard human voice sampling rate used in telephone transmission, which is 8000 Hz or 8000 ...
The actual bandwidth requirement will be slightly more because when these twenty voice signals (channels) are multiplexed to form a frame ... .
