Abstract
A first periodic digital waveform is to be synchronized with a second periodic digital waveform obtained by propagating the first waveform through a delay path (13) having an adjustable propagation delay. In the disclosed approach, the delay of the delay path is increased, even when an edge (43) of the second waveform trails a corresponding edge (45) of the first waveform by less than one-half cycle. The delay continues to be increased until the edge of the second waveform is eventually time-shifted past the next successive corresponding edge (49) of the first waveform.
