What is "frequency modulation"?
Frequency modulation (FM) is a method of transmitting radio signals by varying the frequency, or pitch, of the radio wave. In FM radio, the audio signal, such as music or speech, causes slight changes in the frequency of the carrier wave. This results in a clearer sound and less interference compared to other methods, like amplitude modulation (AM). FM is commonly used for music and high-quality radio broadcasts because it can transmit sound with better clarity and resistance to noise.
Example
Frequency modulation is commonly used in FM radio broadcasting to transmit high-fidelity sound over long distances.
Engineers prefer frequency modulation over amplitude modulation for its resistance to signal interference and noise.
The scientist explained how frequency modulation alters the frequency of the carrier wave to encode information.
