Question -

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



Answer -

Maximum amplitude, Amax = 10 V

Minimum amplitude, Amin = 2 V

Modulation index μ,is given by the relation:
