Abstract
PURPOSE: To prevent the malfunction of the synchronizing separation circuit system, by the gate control with the synchronizing signal separating the chrominance signal which is frequency divided after the frequency modulation at the limiter, from the video signal.
CONSTITUTION: The video signal inputted from the terminal 1 is picked up only for the chrominance signal component at the BPF 2, and after it is frequency modulated at the limiter 3, it is frequency divided 4 and fed to the gate circuit 8 via the BPF 5. On the other hand, the video signal from the terminal 1 is separated for the synchronizing signal at the synchronous separation circuit 1, and gate control is made for the output signal from the BPF 5. Thus, with a simple constitution, the unnecessary signal between the horizontal and vertical synchronizing signals is prevented from being intruded to avoid the malfunction of the synchronizing separation circuit system.
