Frequency Modulation (FM)
Frequency Modulation (FM)
A method of encoding information in a carrier wave by varying its frequency.
FM Formula
FM Formula
fi = fc + Δf ⋅ sin(2πfm t), where fc is the carrier frequency, Δf is the frequency deviation, and fm is the modulating signal’s frequency.
Frequency Deviation (Δf)
Frequency Deviation (Δf)
The maximum amount by which the frequency of the carrier signal changes.
