Sync signals are a necessary part of video systems, but it seems like they are often there when you don’t want them, and conspicuously absent when you need one. Thus, two common functions required for processing analog video signals are sync strippers, to remove unwanted sync signals, and sync inserters to combine separate video and sync signals into one “composite” video signal. An ideal sync stripper or inserter should perform the desired function and drive at least one double terminated video load without degrading the video signal.
