Frequency Modulation
Frequency Modulation (FM) is a method of encoding information in a carrier wave by varying its frequency. In radio broadcasting, for example, sound signals (like music or voice) modulate the frequency of a radio wave instead of its amplitude. This technique allows for better sound quality and less susceptibility to interference compared to amplitude modulation (AM). As a result, FM radio stations can deliver clearer audio, making it a popular choice for music and other broadcasts. It’s widely used in radio, television, and signaling systems, providing reliable communication.

Frequency modulation (FM) is a method of encoding information onto a carrier wave by varying its frequency. In simpler terms, it changes how fast the wave oscillates to represent different signals, such as sound. This technique is commonly used in radio broadcasting, where music and voice are transmitted clearly over long distances. FM is known for its resistance to static and interference, resulting in better sound quality compared to amplitude modulation (AM). Overall, frequency modulation plays a significant role in communications technology, enabling clearer audio and data transmission.
