Description: Frequency modulation (FM) is a technique used to encode information onto a carrier wave by varying its frequency. This technique is based on altering the frequency of a carrier signal according to the instantaneous amplitude of the information signal to be transmitted. Unlike amplitude modulation (AM), where the amplitude of the carrier wave is modified, FM allows for greater resistance to interference and better performance in audio transmission. Frequency modulation is especially valued in applications where sound quality is crucial, such as in broadcasting music and voice. Additionally, its ability to transmit information efficiently has made it a standard in various communication technologies, including data transmission across different devices. In the context of remote control systems, frequency modulation enables the control of devices, ensuring that control signals reach effectively even in environments with high electromagnetic interference.
