Description: 数字选台收音机
注意：
（1）遥控发射芯片用TC9012/TC9243
经常用到的还有UPD6121和LC7461，它们的不同只处在于引导码的时间不同或者数据位的个数不同，接受原理基本一样。将本程序的相关位置修改就可以通用。
系统时钟22.1184MHZ，如果用其他的时钟请将delay.c文件中的定时器装载值修改一下
（2）
键盘检测在VFD程序中，16312可以驱动VFD，另外外部可接24个按键，并将按键值放到
其内部的存储中，使用时只须发命令读即可。
（3）
由于时间原因，只给出调幅波段的自动搜台功能，调频的自动搜台程序和调幅一样，自己写了。
（4）主要用在组合机和功放机上的收音头大部分以LC72171做锁象环，LA1823做高中频处理
和音频解调，但是有的数调收音头把锁象环和高频处理做在一起，典型的有TEA5757和TEA5756
TEA5757采用了一种所谓的自动调谐系统，在自动搜索时无须读中频，简化了程序。-digital radio attention to the election : (1) remote control chip with TC9012/TC9243 launch frequently used were UPD6121 and LC 7461, the only different is that the lead time for different code or data of the number of different spaces, accept the basic tenets of the same. Will be the location of the relevant procedures can be revised definitive. System Clock 22.1184 MHZ. If the clock I would be grateful if other delay.c document loading value of the timer changed a bit (2) keyboard detection V FD procedure, 16312 can drive VFD, and the external access 24 button. and keystroke values into its internal memory, use only the order can be read. (3) For reasons of timing, given only the AM band automatic search function Taiwan FM automatic seizure procedures and Taiwan AM, himself wrote a. (4)

Description: 本设计是一个数字调频收音机，调频就是频率调制，所谓频率调制就是原来等幅恒频的高频信号的频率，随着调制信号（音频信号）的幅度变化而变化，调频收音机（FM Radio）就是接收这些频率调制的无线电信号，经过解调还原成原信号的电子设备。FM Radio电路一般主要由接收天线、振荡器、混频器、AGC（自动增益控制）、中频放大器、中频限幅器、中频滤波器、鉴频器、低频静噪电路、搜索调谐电路、信号检测电路及频率锁定环路、音频输出电路等组成。本设计就是用单片机控制集成了上述所有FM功能的专用芯片，设计一个数字FM收音机系统。
-This design is a digital FM radio, FM is frequency modulation, frequency modulation is the original so-called constant frequency amplitude high-frequency signal frequency, with the modulation signal (audio signal) the magnitude of change, FM Radio (FM Radio) is frequency modulation radio receiving these signals, the demodulated signal to restore to the original electronic equipment. FM Radio is generally mainly by the receiving antenna circuit, oscillators, mixers, AGC (automatic gain control), IF amplifier, IF limiter, IF filter, frequency discriminator, frequency squelch circuit, search tuning circuit, signal detection and frequency locked loop circuit, the audio output circuit. This design is integrated with MCU control all of the above FM function ASIC design of a digital FM radio system.
