Abstract : This patent discloses an apparatus for providing a logical output indicative of when a signal is either in-phase with a reference signal or alternately 180 deg out-of-phase with a reference signal. Pulses are produced at each transition of the waveforms to be compared. A determination of their concurrence is then made and compared with a logical result of the inputs whereby a logical output indicative of whether the signals are in-phase or 180 deg out-of-phase is generated.
