FM (Frequency Modulation)

Frequency Modulation (FM) is a method of transmitting information by changing the frequency of a carrier wave in accordance with the sound or data signal. Instead of altering the wave's amplitude (height), FM varies its pitch (frequency), which makes it more resistant to noise and interference. When you listen to FM radio, the station encodes sound into these frequency changes, allowing for clear audio reception even in challenging environments. This technique is widely used in radio broadcasting because it provides high-quality sound and maintains signal integrity over longer distances.
