  • Average phase position circuit
    Patent number: 4001558
    Abstract: Method and apparatus for phase averaging of two phase position signals to derive a single phase position signal. The apparatus comprises phase discriminators for comparing each of the two phase position signals to the phase of the single phase position signal and a combining circuit for summing the output signals from the phase discriminators to derive an error signal when the single phase position signal is not midway between the phases of the two phase position signals. Circuitry is provided to modify the phase of the single phase position signal in response to the amplitude of the error signal.
