ABSTRACT:
A circuit for measuring the frequency of an electrical signal includes a detector that senses a reoccurring phase point the electrical signal. A divide-by-M counter is connected to the detector and produces a control signal upon every Mth occurrence of the indication, where M is a positive number greater than one. A clock signal generator is provided. An output counter counts cycles of the clock signal between occurrences of the control signal and divides the count by M to produce an output count that corresponds to the frequency of the electrical signal.
