ABSTRACT:
A digital time multiplex communications system for transmission of a time multiplex signal containing the signal elements of a synchronization channel and of a plurality of communications channels. The receiver includes a member for separating the synchronization channel signal element from the communications channel signal elements of each frame. An externally triggerable sawtooth voltage generator connected to the separating member generates a sawtooth voltage sweep in response to the appearance of each synchronization channel signal element. A plurality of comparison stages each associated with a respective communications channel and connected to receive the sawtooth voltage and to produce an output signal when the sawtooth voltage reaches a respective value which differs by a fixed amount from one stage to the next such that the output signal from each stage occurs at a time corresponding to the appearance of a signal element of its associated communications channel.
