  • Frequency adjustment circuit
    Patent number: 4068462
    Abstract: A circuit for adjusting the frequency of operation of an electronic time keeping device, which device includes a source of clock pulses. The circuit of this invention is preferably located between the source of clock pulses and the time keeping device counting circuitry, so that the clock pulses can be periodically interrupted for a programmed amount of time. Accordingly, the variable adjustment capacitor, typically employed in prior art time keeping devices, can be eliminated.
