Did you know?
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. In analog frequency modulation, such as radio broadcasting, of an audio … See more If the information to be transmitted (i.e., the baseband signal) is $${\displaystyle x_{m}(t)}$$ and the sinusoidal carrier is $${\displaystyle x_{c}(t)=A_{c}\cos(2\pi f_{c}t)\,}$$, where fc is the carrier's base frequency, and Ac … See more FM provides improved signal-to-noise ratio (SNR), as compared for example with AM.

WebFeb 21, 2024 · FM Bandwidth Bandwidth is defined as the difference that is between maximum and minimum frequencies of them resultant frequency modulated signal. In amplitude modulation, it is easy to calculate the bandwidth as it is twice the frequency of the message signal. WebThough 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.” If we think of frequency as something that has an instantaneous value, rather than as something that consists of …
