frequency deviation

[¦frē·kwən·sē ‚dē·vē′ā·shən]
(communications)
The peak difference between the instantaneous frequency of a frequency-modulated wave and the carrier frequency.

Deviation, Frequency

 

the change of the frequency of oscillations from its average value. In frequency modulation, the maximum frequency difference is usually called the deviation frequency. The composition and values of the amplitudes of the components of the spectrum of a frequency-modulated oscillation, as well as the freedom from interference of a radio system, depend on the magnitude of the frequency deviation.
