ABSTRACT:
A composite video signal is coupled to the input of a tapped delay line of a vertical sync separator. A detector determines the presence of the vertical sync signal profile within the sampled portion of the composite video. An output signal is produced by the separator when the appropriate vertical sync profile is thus detected.
