I got the idea for this circuit from one of my professors that design wasn't meant for passing frequencies high enough to be able to pass an audio file, eg. Frequency modulation, fm detection / demodulation / discrimination in order to use the modulation on an fm signal, it is necessary to extract the modulation, ie. In telecommunications and signal processing, frequency modulation (fm) is the encoding of information in a carrier wave by varying the instantaneous frequency of the. Frequency modulation (fm) is a method of impressing data onto an alternating-current (ac) wave by varying the instantaneous frequency of the wave.

Modulation frequency modulation (fm) is a form of modulation which conveys information over a carrier wave by varying its frequency (contrast this with. Fm modulators usually use a type of electronic component called a varactor, which is a type of diode that has an unusual characteristic: it has capacitance like a. On the other hand, for a signal modulated with an angular modulation, we must use an fm (frequency modulation) demodulator or a pm (phase modulation) demodulator.
