ABSTRACT:
Composite sync is separated from video despite noisy, weak, or nonstandard signal conditions. Sync is separated from the composite video signal by comparing the video signal to a D.C. reference voltage which is generated depending upon the particular characteristics of the received video signal. Outputted sync signals during vertical sync and nonstandard periods are conditioned for proper phasing in other receiver circuits such as the Horizontal A.P.C.
