frequency modulation

n
(Telecommunications) a method of transmitting information using a radio-frequency carrier wave. The frequency of the carrier wave is varied in accordance with the amplitude and polarity of the input signal, the amplitude of the carrier remaining unchanged. Abbreviation: FM Compare amplitude modulation

frequency modulation

A method of radio broadcasting in which the frequency of the wave that carries the sound signal changes to reflect the various sounds that are to be reproduced, while the amplitude of the wave remains the same. Frequency modulation reduces static in radio transmission. Compare amplitude modulation.
