    To find the modulation index, we need to compare the amplitude of the modulating signal to the amplitude of the carrier signal.

    In this case, the modulating signal is 20 cos 1800?t, which has an amplitude of 20.
    The carrier signal is 5 cos 1600?t, which has an amplitude of 5.

    The modulation index is given by the formula:

    Modulation Index = (Amplitude of Modulating Signal) / (Amplitude of Carrier Signal)

    Plugging in the values, we get:

    Modulation Index = 20 / 5 = 4

    Therefore, the modulation index is 4.
