ABSTRACT:
A phase and frequency detector circuit includes both a phase comparator such as an exclusive-OR gate possessing high phase sensitivity, and a frequency-phase comparator that is sensitive to differences in frequency. The outputs of these circuits are combined to provide a single output signal offering both frequency discrimination and sharp phase discrimination.
