ABSTRACT:
A digital frequency-phase comparator includes a bistable element responsive to first and second frequency input pulse signals for generating a phase error signal, a circuit which includes second and third bistable elements responsive only to the leading edge transition of the input pulse signals in the presence of the outputs from the first bistable element to generate frequency error signals, and a circuit which combines the phase and frequency error signals to provide a triple state output.
