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 be the value of μ if the minimum amplitude is zero volt?
1) 0 2) 3 3) 1 4) 2
SOLUTION
Maximum amplitude, Amax = 10 V Minimum amplitude, Amin = 2 V Modulation index μ, is given by the relation:
