立体声解调器是立体声调频接收机的关键部分。近两年来,锁相环式集成电路立体声解调器(以下简称 PLL 立体声解调器)以其性能优良稳定,外电路简单,调整方便等特点,迅速地取代了其它各种形式的立体声解调器。目前,我国正在试制或已投产的各种立体声收录机、立体声调谐器已普遍采用了这种器件。LA3361、HA11227、AN7410三种型号的进口解调器集成块是近期各整机厂采用较多的产 Stereo demodulator is a key part of the stereo FM receiver. In the past two years, the PLL stereo demodulator (hereinafter referred to as the PLL stereo demodulator) has rapidly replaced other various forms of stereo demodulation due to its excellent performance and stability, simple external circuit and convenient adjustment Device. At present, our country is trial or has put into operation a variety of stereo recorders, stereo tuner has been widely used in this device. LA3361, HA11227, AN7410 three models of the import demodulator manifold is the recent use of the entire plant more production
