CIRCUIT ARRANGEMENT FOR SYNCHRONIZING AN OUTPUT SIGNAL IN ACCORDANCE WITH A PERIODIC PULSATORY T SIGNAL

摘要

Synchronizing circuit arrangement, for example for line synchronization in a television receiver, including digital means, the frequency of the oscillator being twice that of the signal to be synchronized. A frequency divider circuit, for example a master-slave flipflop, produces two output signals one of which serves as a reference signal for the phase discriminator whilest the other is applied together with the input signal of the circuit to a coincidence stage.
