Abstract
A digital sync separator has a separator for supplying composite sync from composite video. A counter counts clock pulses and is reset by the composite sync signals and one of its outputs. The separator can comprise a pair of controlled switches, one switch being a clamp, the other supplying a signal to a low pass filter and attenuator, and a comparator to compare the composite video with the attenuated signal.
