Understanding FM Radio - How It Works and Its Significance

FM stands for Frequency Modulation. It is a type of radio broadcasting where the frequency of the radio signal is varied in accordance with the audio signal being transmitted. This variation in frequency causes the radio receiver to demodulate the signal and extract the original audio information.

In simple terms, FM radio works by modulating the frequency of the radio signal to encode the audio information, and then demodulating the signal at the receiving end to retrieve the original audio. The modulated frequency is then used to produce the sound that we hear on our radios.
