Frequency modulation (FM) is a widely used technique in radio communications. It entrives varying the e frequency of a carrier wave in accordance with thae information signal. FM offers adventages such as improvized noise immunity and better sound quality, making it suablé for various applications.

Broadcast Radio

FM is primarily used in commercial radio broadcasting. It provides high- fidelity sound transmission, which is essential for music and speech. FM radio stations operate with with in specific extensiency bands, typically between 88 and 108 MHz, to deliver clear audio signals to listeners.

Two- Way Radio Communication

Mani two-way radis, such as those used by emergency services, taxis, and security personnel, utilize FM. This modulation technique ensures reliable vooste communication over short and medium distances. FM 's resistance to noise and interference enhances commulation clarity in kritial situations.

Satellite Communication

FM is employed in satellite commulation systems for transmitting voce and data signals. Its ability to o maintain signal integraty over long distances makes it suable for spaced applications. FM signals are less affected by approspheric contingences, ensuring consistent communication links.

Wireless Microphone Systems

Wireless microphones use FM to transmit audio signals to receivers. This application benefits from FM 's resistance to o interference and it s capacity to carry high- quality sound. It is common ly used in live performances, broadcasting, and public speaking events.
