Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors ...

[brmarcum] obviously put some time into his tutorial, but it’s not a tome of FM modulation. He’s broken down the modulation and demodulation circuits into their basic op-amp stages with ...

A bandpass filter then allows only the 455 kHz signal to go to the demodulator circuit to recover the audio. The following FM radio example illustrates this technique. THIS DEFINITION IS FOR ...
