Amplitude of Each Sideband Formula

Amplitude of each Sideband = (Modulation Index*Amplitude of Carrier Signal)/2
A_sb = (μ*A_c)/2

Why does amplitude modulation create sidebands?

When the signal is modulated onto the carrier in the electromagnetic spectrum, that signal occupies the small portion of the spectrum surrounding the carrier frequency. It also cause sidebands to be generated at frequencies above and below the carrier frequency.

How to Calculate Amplitude of Each Sideband?
