ABSTRACT:
Disclosed is a circuit for locking a harmonic-rich oscillator, such as the crystal-controlled type, to provide as its output, a signal at a designated frequency characterized by minimum harmonic content and high stability. The circuit includes a combination of gates in the oscillatory feedback path controlled by single-shot multivibrators with time constants such that any tendency of the period of the output signal to compress or expand is overridden by the respective expansion or compression thereof by the appropriate single-shots.
