Time division multiplexing (TDM) is a technique that shares
a transmission channel between users by dividing transmission time by
allotting to each device a time slot during which it
can send or receive data. Time division multiplexing involves
interleaving in time the narrow pulses of pulse-code modulation (PCM)
or delta modulation (DM) to form one composite digital signal
for transmission. De-multiplexing of the time-multiplexed pulse streams at the
receiver is accomplished by gating appropriate pulses into individual channel
filters.
