FM, abbreviation for frequency modulation

FM: see modulation modulation, in communications, process in which some characteristic of a wave (the carrier wave) is made to vary in accordance with an information-bearing signal wave (the modulating wave); demodulation is the process by which the original signal is recovered from

Fm, chemical symbol

Fm, symbol for the element fermium fermium [for Enrico Fermi], artificially produced radioactive chemical element; symbol Fm; at. no. 100; mass no. of most stable isotope 257; m.p. 1,527°C;; b.p. and sp. gr. unknown; valence +2, +3. Fermium is a member of Group 3 of the periodic table.

FM

in full frequency modulation

Variation of the frequency of a carrier wave (commonly a radio wave) in accordance with variations in the audio signal being sent. Developed by American electrical engineer Edwin H. Armstrong in the early 1930s, FM is less susceptible to outside interference and noise (e.g., thunderstorms, nearby machinery) than is AM. Such noise generally affects the amplitude of a radio wave but not its frequency, so an FM signal remains virtually unchanged. FM is also better able to transmit sounds in stereo than AM. Commercial FM broadcasting stations transmit their signals in the frequency range of 88 megahertz (MHz) to 108 MHz.

1.	(communications)	FM - Frequency Modulation.
2.	(jargon)	FM - Fucking Manual, a back-formation from RTFM. Used to refer to the manual itself.
3.	(jargon)	FM - Fucking Magic, in the sense of black magic.
4.	(networking)	fm - The country code for the Federated States of Micronesia. Heavily used for vanity domains by FM radio stations.
