| - The Frequency Modulation skill increases the falloff range of many types of ECM modules.
- In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (in contrast with amplitude modulation (AM), in which the amplitude of the carrier wave is varied while its frequency remains constant). In analog applications, the difference between the instantaneous and the base 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.
- FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech (see FM broadcasting). Normal (analog) TV sound is also broadcast using FM. A narrow band form is used for voice communications in commercial and amateur radio settings. The type of FM used in broadcast is generally called wide-FM, or W-FM. In two-way radio, narrowband narrow-fm (N-FM) is used to conserve bandwidth. In addition, it is used to send signals into space.
- Frequency modulation, or FM, was a method of radio communications which involved slightly varying the frequency of the transmission being sent. This was different from amplitude modulation, which varied the strength of the signal. FM radio transmissions were detected coming from the planet 892-IV in 2268 by Uhura on board the USS Enterprise.

When the modulation is of audio frequency, the result is a composite waveform containing a complex frequency spectrum mathematically related to the frequencies of the individual harmonics contained within the carrier and the modulation.As it happens, frequency modulation is capable of mimicking the harmonic content of a wide variety of acoustic instruments, ranging from piano to trumpet to sitar. The Yamaha DX-7 synth of the 1980s exploited this characteristic to great effect.FM has a reputation for being a difficult method of synthesis to program sounds in; it is not always easy to know how to approach getting a particular type of sound or predict in advance the results of a particular patch. Compare with amplitude modulation.
