ABSTRACT:
A time division multiplex transmission system includes: a time division multiplex encoder for supplying a master clock to a plurality of PCM digital signal sources having a same sampling frequency and a same quantization bit number to effect clock synchronization and generating a time-divisionally multiplexed data signal based on a data word not D/A converted and sampled from each digital signal source; a transmission line for transmitting the multiplexed data signal from the time division multiplex encoder; and a time division demultiplex decoder for selecting a desired transmitted, multiplexed data signal and demultiplexing the selected data signal in accordance with a transmission rate before the time division multiplexing.
