Abstract
PURPOSE: To reduce the phase difference between two input signals, by detecting the phase difference between the signal of the IF amplifier and the reference carrier signal in the synchronous detection system, controlling the center frequency of the frequency discriminating signal of the AFT circuit with this detection signal, and correcting the local oscillating frequency.
