Abstract
A linear three-state phase detector capable of accurately responding to simultaneous input signals has its linear range extended by uniquely sensing cycle slip and stepping a binary up-down counter. The cycle slip detector is capable of handling simultaneous inputs by determining that a resulting change of the three-state phase detector output occurs after a predetermined time after an input signal.
