新型调频接收机的电路原理与性能特点

Principle and Feature of a New Pattern FM Receiver

介绍了一款采用TDA7088T的新型调频接收机,其主要优点是将混频器、中频放大器、立体声解调器以及静噪电路、选频电路和振荡电路集成在一起;同时还有自动频率控制和电子调谐等功能。重点介绍了这种接收机的设计思路和工作原理以及各相关部分的特性。

This paper has introduced one kind of the new pattern frequency modulation receiver sets by the use of TDA 7088Tn,whose primary excellence lies in making the related devices inegrated together,such as the mixer,the intermediate frequency amplifier the stero demodulator, the same time, the reteiver set takes the advantages others are its automatic frq\equency control function and electronic tuning function. This paper primarily introduces the design scheme and the qorking priinciple for the receiver along whth the characteristics of ts relataed parts.
