Abstract
A signal processing system for obtaining a continuous signal, phase locked to a signal subjected to timing variations. The continuous signal phase locked to a signal subjected to timing variations is obtained from a variable oscillator, whose oscillation is controlled according to an error signal produced from a phase comparator in accordance with the phase difference between the signal subjected to timing variations and a higher-frequency signal produced from the output of said variable oscillator in the presence of a fixed oscillator.
