Abstract

PURPOSE:To simplify the calibration operation and to prevent the malfunction by providing the automatic calibration circuit to the output side of the phase discriminator to make the phase difference meter show the zero point at the calibration time of a receiver and then controlling the phase shift with the output of the discriminator.
