Answer :

Let the amplitude of the carrier signal be Ac and the amplitude of the message signal be Am.

Maximum amplitude, _______(1)


Minimum amplitude, _______(2)


Adding both the equations, we get




Subtracting (2) from (1), we get




The modulation index is given by:




Hence, the modulation index is 2/3.
