System for simultaneous transmission of several pulse trains |
摘要 |
A main pulse train at a main frequency and at least two derived pulse trains at submultiples of the main frequency are transmitted over a transmission path, from a transmitter to a receiver, in the form of pulses of alternating polarity. A first one of the derived pulse trains is transmitted as a single violation of bipolarity in the main pulse train while a second one of the derived pulse trains is transmitted as two successive violations of bipolarity in the main pulse train. The system is applicable to multiple synchronization (bit, frame etc . . . ) in a PCM digital transmission or switching system.
