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.
May 15, 2024 · Frequency Modulation or FM is a method of encoding information on one carrier wave by changing the wave carrier frequency. Frequency Modulation technology is used in the fields of computing, telecommunications, and signal processing.
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.
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.”
Definition: A category of angle modulation in which the frequency of the carrier wave is changed according to the amplitude of the message signal is known as frequency modulation. It is abbreviated as FM and is a widely used analog modulation technique.
Unlike amplitude modulation, which varies the strength of the signal to convey the data, frequency modulation alters the frequency of the carrier wave. This modulation technique offers several advantages, such as improved signal quality, reduced interference, and enhanced bandwidth usage.
Frequency modulation is a straightforward approach for simple biomimetic encoding, as it is strongly related to how information is represented in the spiking rate. Experimental results using pulse frequency modulation to encode applied force confirmed this strategy as valid (Graczyk et al., 2018; Ortiz-Catalan et al., 2014).
Frequency modulation, (FM), variation of the frequency of a carrier wave in accordance with the characteristics of a signal. See.
As explained last month, audio-frequency modulation of the amplitude of a signal can be a powerful synthesis tool. The possibilities expand still further when we consider what happens when you use one audio-frequency signal to modulate the frequency of another...
Frequency modulation is another way of encoding a signal on a carrier wave. The carrier amplitude remains constant but the frequency of the carrier is modulated. This change is usually constrained, so the carrier frequency changes over a small range.
