A carrier wave is modulated by n number of sine waves with modulation indices `mu_(1),mu_(2),mu_(3)+`.... The total modulation index `(mu)` of the wave isA. `mu_(1)+mu_(2)+mu_(3)+`....B. `sqrt(u_(1)^(2)+mu_(2)^(2)+mu_(3)^(2)+....)`C. `[(mu_(1)^(2)+mu_(2)^(2)+mu_(3)^(3)+....)/(n)]^(1//2)`D. `[(n)/(mu_(1)^(2)+mu_(2)^(3)+mu_(3)^(2)+......)]^(1//2)` |
