Title: Time division multiplex transmission system

Abstract: A time division multiplex transmission system for communication of a data signal in a time-multiplex fashion over a data signal transmission path comprises a clock pulse generator for generating two-phase clock pulses including a first train of one phase and a second train of opposite phase. The system further comprises a plurality of transmitters and receivers, each including a wave shaper for demodulating the two-phase clock pulses and producing a single-phase clock pulse train, and a station selection circuit for processing the single-phase clock pulse train to identify that period of time during which the particular transmitter or receiver is selected for transmission or reception. Each transmitter and receiver also comprises a reset signal detector circuit, responsive to the detection of an intermission period in the clock pulse train, to reset the station selection circuit of the particular transmitter or receiver, thus achieving overall synchronization of the transmitters and receivers in the system.
