Vedclass · Answer

(C) When multiple sine waves with modulation indices $n_1, n_2, n_3, \dots$ modulate a single carrier wave, the total modulation index $n$ is given by the square root of the sum of the squares of the individual modulation indices.This is because the total power of the modulated wave is the sum of the powers of the individual components.The total modulation index is defined as $n = \sqrt{n_1^2 + n_2^2 + n_3^2 + \dots}$.

If a number of sine waves with modulation indices $n_1, n_2, n_3, \dots$ modulate a carrier wave, then the total modulation index $(n)$ of the wave is:
