What is a FM receiver?

Question

What is a FM receiver? How does it work? Thanks in advance.

Answer 1

Frequency modulation was invented in the States in 1938. Amplitude modulation imposes the signal on the carrier wave by varying the strength of the carrier wave. FM varies its frequency instead. Its advantage over AM is that you get a better quality received signal; less noise, so it's often used for high quality music broadcasts. It's also used for air traffic control in the immediate vicinity of the airport. A minor disadvantage is that the circuitry is more complex. It takes up more bandwidth, so it isn't suitable for long distance short wave broadcasts; there wouldn't be enough frequencies for all the stations in the world.

Answer 2

Hi. Frequency Modulation means that a signal, usually audio, is used to vary the carrier frequency of a signal by increasing and decreasing it. The FM receiver can recover the audio signal, say, by the use of a demodulation circuit.

Answer 3

It is a receiver which has the capacity to demodulate a signal that was frequency modulated.
With FM, the center frequency of the carrier is skewed up and down in synchrony by the signal used to modulate it.
