Abstract

PURPOSE: The secondary winding is provided to a selective transformer used for a synchronizing detection circuit and a carrier signal is picked out from this secondary winding to eliminate the variation in carrier due to the extraction of the carrier signal, thereby obtaining a normal setection signal.
