A system for varying the relative time delay between two broadband input signals consisting of an adjustable time delay coupled to one of two input channels of a two point clipper correlator. The correlator includes a plurality of cross-coupled exclusive OR gates which generate output signals only when the correlation functions of both channels correspond. Decisions made in the correlator at each sample time are used to vary the adjustable delay, to provide automatic tracking of the peak of the cross-correlation function between the input signals.
