For an amplitude modulated wave, the maximum amplitude is found to be 10 V while the minimum amplitude is found to be 2 V. Determine the modulation index μ. What would be the value of μ if the minimum amplitude is zero volt?

Ans : Maximum amplitude, A_max = 10 V

Minimum amplitude, A_min = 2 V

Modulation index μ, is given by the relation:
