Sagedusmuutust
Sagedusmuutust, also known as frequency modulation (FM), is a method of encoding information on a carrier wave by varying its frequency. The carrier wave is a radio wave with a constant amplitude and frequency, which is then modified by the information signal. The information signal, also called the modulating signal, can be an audio signal, a video signal, or any other type of data.
In FM, the frequency of the carrier wave is changed in proportion to the amplitude of the
FM is widely used in radio broadcasting, particularly for music and high-fidelity audio, due to its ability
