FMbroadcastsüsteemid, also known as FM broadcasting systems, are a technology used for transmitting audio signals wirelessly over radio waves. These systems utilize Frequency Modulation (FM) to encode audio information onto a carrier wave. In FM, the frequency of the carrier wave is varied in accordance with the amplitude of the original audio signal. This method is known for its superior sound quality and resistance to static and interference compared to Amplitude Modulation (AM) systems.

The fundamental components of an FM broadcast system include a transmitter, an antenna, and a receiver. The transmitter generates the carrier wave and modulates it with the audio signal. This modulated signal is then amplified and sent to the transmitting antenna, which radiates the radio waves into the atmosphere. Receivers, typically radios, are tuned to a specific frequency allocated to a particular FM station. The receiver's antenna captures the radio waves, and the receiver then demodulates the signal, extracting the original audio, which is then reproduced through a speaker.

FM broadcasting operates within specific frequency bands, with 88 to 108 MHz being the most common range for public radio broadcasting in many parts of the world. This band allows for a significant number of stations to operate simultaneously without excessive interference. FM systems are widely used for music broadcasting, talk radio, and public service announcements due to their fidelity and reliability.
