Abstract
A receiver for receiving a composite signal including a multivalue pulse code modulated information signal and a binary pulse code modulated synchronizing signal and for regenerating the information signal. The receiver comprises an identification circuit for the identifying binary pulse code signal and an identification circuit for identifying the multivalue pulse code signal to both of which the received composite signal is supplied. The synchronizing signal is detected and regenerated by using the identified signal identified by the identification circuit for identifying the binary pulse code signal. Also by using the regenerated synchronizing signal, the composite signal is pulse clamped and the pulse clamped composite signal is supplied to the identification circuit for identifying the multivalue pulse code signal and the identification is effected.
