An FM radio is designed to receive the modulated signal at the proper frequency in order to give you the audio of the station you are listening to.FM radios are included in a wide number of electronic devices today and all work the same way,though the elements that make it happen vary.
The signal from an FM transmitter is broadcast in a manner that envelopes the listening area with relatively constant signal strength.It is because of this that FM radio has the advantage of being received in areas where an AM signal would not be received.The circuitry in an FM radio uses the antenna usually built into the radio to catch signals as they present themselves in the area of the radio.The signal is taken into the radio and converted into a voltage the FM circuitry converts into sound.In particular,the circuitry detects the carrier wave and the modulated signal and converts that modulated signal into sound while steering the signal to the right place on the dial using the carrier

答案

调频收音机设计用来以适当的频率接收调制信号,从而使您能够听到您正在收听的电台音频.如今,许多电子设备中都内含了调频收音机,即使一些因素使得这些收音机有所不同,但它们都是在以同样的方式工作.从调频发射器发出的信号以相对持续的信号强度涵盖收听区域的方式进行广播.这是因为调频收音机具有能在无法接收调幅信号的区域接收信号的功能.调频收音机的电路使用天线（通常为内置式）捕捉在收音机区域出现的信号,而信号则会被收音机接收并转换成电压,之后在转换成声音.尤其是,当使用载波将信号调到正确的选台显示器上时,电路会探测到载波和调制信号,并将此调制信号转换成声音.
