ABSTRACT:
A noise immunity circuit incorporates a first channel for tracking a train of periodic sync pulses and for locking a window to said pulses for rejecting spurious noise signals. A second channel senses when the sync pulses are displaced in phase and establishes a new rephased window that is in phase with the displaced sync pulses.
