Frequency modulation ( FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing .
Frequency modulation is a technique or a process of encoding information on a particular signal (analogue or digital) by varying the carrier wave frequency in accordance with the frequency of the modulating signal.
May 15, 2024 · Frequency Modulation is a process of encoding information on one carrier wave by changing its frequency. The frequency of the carrier wave is changed according to the frequency of the modulating signal. Frequency modulation is used for broadcasting and radio communication.
A category of angle modulation in which the frequency of the carrier wave is varied according to the amplitude of the modulating signal is known as frequency modulation. It is abbreviated as FM and is most extensively used analog modulation technique.
Nov 10, 2022 · Definition, Derivation, Waveform & Formula. The process of modulation in which the frequency of the carrier signal is changed according to the instantaneous magnitude of the modulating signal is known as frequency modulation. Fig. 1: Frequency Modulation.
Frequency Modulation: Theory, Time Domain, Frequency Domain. PDF Version. Though less intuitive than amplitude modulation, frequency modulation is still a fairly straightforward method of wireless data transmission. We are all at least vaguely familiar with frequency modulation—it’s the origin of the term “ FM radio.”.
At its core, frequency modulation involves changing the frequency of a carrier signal in accordance with the input signal. The input signal, which carries the message to be transmitted, is used to modulate the frequency of the carrier wave.
