摘要：
Disclosed is a synchronization circuit that can be applied in the field of monitors and, especially, in the field of television receivers. The disclosed circuit comprises circuits to analyse and correct the horizontal and vertical synchronization signals in order to neutralize the effect of the signalling present in the horizontal synchronization signal on the working of a phase-locked loop.
