The standard enables one to reproduce the unit of frequency deviation in hertz (Hz) and to transmit the dimensions of the unit using working standards of the working measuring instruments.

What is frequency deviation formula?
The toned (single frequency) modulating signal consists of only one frequency component and this signal is modulated with a carrier signal. For tone modulation, the frequency deviation is. ∆ f = k f A m. Where, is the amplitude of modulating signal.
How is FM deviation measured?
f(t) = f0 + ∆f(t) Peak deviation: In the case of frequency modulation, the peak deviation ∆f is the absolute maximum of the difference between the unmodulated carrier frequency (f0) and the instantaneous frequency f(t).
What is frequency deviation rate?
Frequency deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency.
What is the frequency deviation constant?
Thus an FM transmitter is said to have a modulation sensitivity,represented by a constant, kf, of so many kHz/V, kf = frequency deviation/V = kf kHz/V. The Greek letter δ represents the frequency deviation and fm represents the modulating frequency that causes the deviation.
