Abstract
이 발명은 멀티모드의 동기를 가지는 TV, 모니터등에서 항상 일정한 극성의 동기를 얻기 위한 것으로서, 동기 입력의 극성을 판별하여 2개의 플립플롭이 교대로 성극성의 출력을 발생하고, 이 정극성의 동기만을 출력하도록하여 모드변환에 무관하게 항상 일정한 극성의 동기를 출력하도록 하였다.The present invention is to obtain a synchronization of a certain polarity at all times in a TV, a monitor, etc. having a multi-mode synchronization, the polarity of the synchronization input is determined, the two flip-flops alternately generates a polarity output, and outputs only this polarity synchronization So, regardless of the mode conversion, it always outputs the synchronization of constant polarity.
