FM

modulation of the frequency of a wave; broadcast system which uses this modulation method

.fm is the country code top-level domain (ccTLD) for the Federated States of Micronesia, a group of islands located in the Pacific Ocean. Except for reserved names like .com.fm, .net.fm, .org.fm and others, any person in the world can register a .fm domain for a fee, much of the income from which goes to the government and people of the islands. The domain name is popular (and thus economically valuable) for FM radio station websites (other similar ccTLDs are .am, .tv, .cd and .dj).

FM can refer to:In science and engineeringFrequency modulation, the carrying of information over an electromagnetic wave by varying its frequency. Its most common applications are:FM broadcasting, used primarily to broadcast music and speech at VHF frequenciesFrequency modulation synthesis, a sound-generation technique popularized by early digital synthesizersFm, the chemical symbol for FermiumFerrous metal, any ferromagnetic metal (iron, nickel, cobalt, neodymium, or praseodymium)Fathom, a marine unit of lengthfm, the symbol for femtometre, an SI unit of length (also known as the fermi)File manager, in computing.fm, country-code top-level domain (ccTLD) of the Federated States of MicronesiaFM Towns, one of a line of personal computers by FujitsuTitanium tetrachloride, a chemical found in some smoke screens

In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant). In analog applications, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal.  Digital data can be sent by shifting the carrier's frequency among a set of discrete values, a technique known as frequency-shift keying.
