调频接收机（FM Radio）一直在人们的生活娱乐中占有非常重要的地位，从老式的晶体管收音机到今天的网络收音机，诸如MP3、智能手机、便携式Video播放器等产品中嵌入FM部分。基于FM Radio的广泛应用，本设计主要研究利用单片机实现接收的智能控制。利用所学的高频知识和单片机知识，通过硬件、软件两方面的设计实现功能。- According to the demand of my design,I utilized the digital frequency

Synthesizing technology to form the electric parts of the frequency modulatiom receiver.This receiver owns the functions of tuning and selecting channel,seaching and so on,In my paper,I emphasized on the FM

Frequency tuning circuit that consists of the ICs CXA1019S from Sony

Corp,the phase locking loop circuit formed by BU2614 PLL frequency synthesizer,MCS51 monolithic processor and the other circuits of keyboards,screen and storage.
