FM is a method of transmitting radio waves that can be used to broadcast high quality sound. FM is an abbreviation for `frequency modulation'. Federated States of Micronesia (in Internet addresses). The symbol for the element fermium. fathom. frequency modulation a system used for broadcasting radio programmes AM. 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
modulation of the frequency of a wave; broadcast system which uses this modulation method
Frequency Modulation One of three basic ways (see AM and phase modulation) to add information to a sine-wave signal: the frequency of the sine wave, or carrier, is modified in accordance with the information to be transmitted
Frequency Modulation FM is a radio broadcast band in the broadcast spectrum different from that used by AM stations There is no static in FM radio reception
Frequency Modulation; a method of impressing data onto an alternating-current (AC) wave by varying the instantaneous frequency of the wave The scheme can be used with analog or digital data
Frequency Modulation A modulation technique where the power of a radio transmitter is constant, but its frequency varies in proportion to the modulation Used for broadcast in the FM band, LMR and for the sound on analogue TV
a radioactive transuranic metallic element produced by bombarding plutonium with neutrons
Short for Frequency Modulation, an FM radio in R/C is considered a better radio than the cheaper AM radios because an FM radio will have less glitching than an AM radio Most hobbyists will be fine with an AM radio, but racers can benefit from FM or PCM radios
Frequency Modulation A method of encoding information in which the width (frequency) of signals are varied
Frequency Modulation; modulation of the RF carrier frequency Also the best quality radio format
Frequency Modulation One of the principal methods for transmitting information using radio waves by superimposing the information signal onto a radio frequency carrier wave The frequency of the carrier wave is varied in accordance with the time-varying amplitude of the input signal The amplitude of the carrier wave remains unchanged
Frequency Modulation Modulation technique in which signals of different frequencies represent different data values Compare with AM and PAM See also modulation
