The meaning of FREQUENCY-MODULATED is modulated by frequency modulation : of, using, or relating to waves so modulated.
In Frequency Modulation (FM), the frequency of the carrier changes in accordance with the input analog signal, while the amplitude of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. The key concept and the underlying ...
The meaning of FREQUENCY MODULATION is modulation of the frequency of the carrier wave in accordance with speech or a signal; also : fm.

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...
