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 in FM?
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. The FM signal's instantaneous frequency changes with time around the carrier frequency ω ω ω C .
What is frequency deviation ratio?
Deviation Ratio: The modulation index corresponding to maximum deviation and maximum modulating frequency is called deviation ratio. Deviation Ratio= Maximum Deviation. Maximum modulating Frequency. = δ
What is frequency modulation formula?
The mathematical equation of frequency modulation
The frequency modulation equation includes: v = A sin [ wct + (Δf / fm) sin wmt ] Here, A is the amplitude of frequency modulation signals. ∆f is the frequency deviation.
How to calculate frequency deviation of angle modulated signal?
The difference between FM modulated frequency (instantaneous frequency) and normal carrier frequency is termed as Frequency Deviation. It is denoted by Δf, which is equal to the product of kf and Am. FM can be divided into Narrowband FM and Wideband FM based on the values of modulation index β.
