  • Patent number: 4099125
    Abstract: A circuit for correcting frequency errors in an incoming signal that includes a particular frequency signal. The circuit includes dual phase locked loop circuitry for providing a frequency feedback control, detecting circuitry for detecting the presence of the particular coded signal and generating a hold signal, and a sample and hold circuitry disposed in the feedback path of the phase locked loop circuitry and responsive to the hold signal for setting the feedback control at a particular value to provide an optimal frequency error correction for the particular frequency signal and for holding the feedback control at the particular value for the entire spectrum of the incoming signal, whereby the frequency feedback control set for the particular frequency tone is used for the entire spectrum of the incoming signal to minimize the error in the output frequencies of the circuit.
