ABSTRACT:
A system for communicating digital data which utilizes a synchronization eme in which a transmitter transmits a binary 1 followed by n data bits which are followed by n + 1 binary 0's and in which a receiver is synchronized with the transmitter by generation of a master clock in response to receipt of the transmitted binary 1 and by initiation of a frame pulse having a pulse duration equal to the duration of the incoming data frame.
