Question

How to draw graphs of amplitude modulated wave with values?

Answer 1

Let Amax and Amin be the maximum and minimum amplitudes of the modulated wave. We will get the maximum amplitude of the modulated wave, when cos(2πfmt) is 1. We will get the minimum amplitude of the modulated wave, when cos(2πfmt) is -1. The ratio of Equation 7 and Equation 6 will be as follows.
