Find the amplitude of side bands in the above problem in terms of modulation index `mu` and carrier wave amplitude `A_c`.

Find the amplitude of side bands in terms of modulation index mu and carrier wave amplitude A_c .

Amplitude modulation index mu determines

Amplitude modulation index mu determines

Write an expression for amplitude modulated carrier wave .

A: If the amplitude of a message signal is half of the amplitude of the carrier wave, then the index of modulation is 50%. R: In amplitude modulation the amplitude of the carrier wave varies in accordance with the signal voltage of the message signal.

The modulation index mu in Amplitude modulating, value is

Why is the amplitude of modulating signal kept less than the amplitude of carrier wave ?
