Vedclass · Answer

(C) When a carrier wave is modulated by multiple sinusoidal signals with modulation indices $n_1, n_2, n_3, ...$,the total modulation index $n_t$ is given by the square root of the sum of the squares of the individual modulation indices.This is derived from the expression for the total amplitude of the sidebands in amplitude modulation.The total modulation index is calculated as $n_t = \sqrt{n_1^2 + n_2^2 + n_3^2 + ...}$.

If multiple waves with modulation indices $n_1, n_2, n_3, ...$ modulate a carrier wave,what is the total modulation index of the resulting wave?
