Frequency modulation

Frequency modulation (FM) is a method of encoding information onto a carrier wave by varying its frequency. It is commonly used in telecommunications and broadcasting to transmit audio and video signals over long distances.

About

It is commonly used in telecommunications and broadcasting to transmit audio and video signals over long distances. In FM, the frequency of the carrier wave is modulated according to the amplitude of the input signal. This results in a signal that is less susceptible to interference and noise compared to other modulation techniques such as amplitude modulation (AM). FM signals exhibit properties such as constant amplitude and high signal-to-noise ratio, making them ideal for high-fidelity audio transmission. FM is also used in various applications including radio communication, radar systems, and wireless networking. This Wikipedia page provides a comprehensive overview of FM, its history, mathematical representation, modulation index, demodulation techniques, and practical applications.
