Abstract
PURPOSE: To make it possible to use one terminal as a comparison signal input terminal of saw tooth wave signals and an output terminal of an AFC circuit commonly, by using a capacitor of an integrating circuit also as an output capacitor of a phase detector circuit and controlling the oscillated frequency by a charge and discharge quantity of the capacitor.
