Frequency modulation - Wikipedia

WebFrequency 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, … Webelectromagnetic spectrum. Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the … 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. Compared with an optimum AM scheme, FM typically has poorer SNR below a certain signal level called the noise threshold, but above a higher level – the full improvement or … See more Doppler effect When an echolocating bat approaches a target, its outgoing sounds return as echoes, which are Doppler-shifted upward in frequency.
