Abstract
An instantaneous comparison unit with an associated sequential state logic circuit is described which functions to maintain a condition of phase locking with a reference signal which is substantially immune to disturbances which cause losses or additions of signal fronts. Continuous phase shifting conditions during the transient, which precedes phase locking, is detected and compensated for by the disclosed circuit.
