The maximum amplitude of an amplitude modulated wave is 16 ~V , while the minimum amplitude is 4 ~V . The modulation index is

Options

  1. A0.4
  2. B0.5
  3. C0.6
  4. D4

Correct answer

C. 0.6

Step-by-step solution

We have, m= A_m A_c = E_ -E_ E_ +E_ Here, E_ =16 ~V and E_ =4 ~V aligned & m= 16-4 16+4 & = 12 20 = 3 5 =0.6 aligned
