ABSTRACT:
Apparatus for generating a signal indicative of the phase of a selected pulsed single frequency signal in a background of noise. A first averaging phase detector generates the average phase of the selected signal. A second averaging phase detector generates the average phase of a quadrature signal. Pulse phase averagers compensate for noise in the average phases. A quadrature logic section selects the first average phase when it varies linearly, and selects a phase proportional to the guadrature phase when the first phase varies non-linearly.
