对噪声抵抗能力的增强是PWM相对于模拟控制的另外一个优点,而且这也是在某些时候将PWM用于通信的主要原因。从模拟信号转向PWM可以极大地延长通信距离。在接收端,通过适当的RC或LC网络可以滤除调制高频方波并将信号还原为模拟形式。 -Noise resistance to increasing ability of the PWM is relative to the simulation control another advantage of, and this also is in some

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
