ABSTRACT:
A periodically adjustable frequency generator having as the source of the equency signal a voltage controlled crystal oscillator. A power supply provides a continuous voltage to the oscillator which corresponds to the initial operating frequency. As a periodic error correction signal is received, it is fed through a delay circuit and then to a holding circuit which has an output equal to the last received input. The output of the holding circuit is summed with the power supply signal to provide a corrected voltage signal to the voltage controlled crystal oscillator.
