What is FM Demodulator?
AN FM demodulator is an electronic circuit that accepts a frequency modulated RF carrier frequency (intermediate frequency) on it`s input and produces an audio frequency on it`s output that is proportional in amplitude to the audio frequenc... Read More »

What is the result of demodulating an FM signal?
You get the original modulating signal but with a narrower bandwidth. Example: If it were an audio signal was applied to modulate an FM transmitter, the receiver amplifies the received signal from the antenna, passes it through a bandpass f... Read More »

How do FM modulation and demodulation work?
In FM modulation, the carrier frequency is modulated (varied) by a frequency corresponding to the information to be transmitted. i.e., it may vary +/- 5 khz for an audio component. The components needed are an oscillator for the carrier fre... Read More »

Most likely the capacitance of the electret microphone and the inductance of connecting wire is acting like a tank circuit. This is allowing the FM signal to get into the amplifier where it is most likely being detected and amplified. Usual...

FM demodulators tend to "lock" on a particular carrier and demodulate that. Generally radio station frequencies are assigned so as they are far enough in carrier frequecy, from stations located relatively geographically local. Tropospheric ...
