Abstract
A phase detector for digital signals, such as television sync signals, provides a signed short path output of the phase difference between the signals. It features a means for determining which of the signals is leading and lagging, which means also provides the sign signal. A window signal is generated and clock pulses are counted during the duration of this signal. A register can provide an exact phase difference measurement or a coarse/fine output signal can be provided.
