What is amplitude modulation?

(a) What is amplitude modulation? Draw a diagram showing an amplitude modulated wave obtained by modulation of a carrier sinusoidal wave on a modulating signal. (b) Define the terms (i) modulation index, and (ii) side bands. Mention the significance of side bands.

Amplitude modulation is the process of

The frequency of amplitude modulated wave is equal to

An amplitude modulated wave is as shown in figure. Calculate (i) the percentage modulation, (ii) peak carrier voltage and , (iii) peak value of information voltage.
