frequency modulated signals

Frequency modulated (FM) signals are a type of radio wave where the information (like music or voice) is carried by varying the frequency of the wave rather than its amplitude. Imagine a siren whose pitch changes to encode sound; as the sound varies, the siren’s tone shifts accordingly. In FM transmission, these frequency changes are used to efficiently send sound signals through the air with reduced noise and interference. This method is commonly used for high-quality radio broadcasts because it provides a clearer sound with less distortion.
