    M) is defined as the ratio of the amplitude of the modulating signal (Vm) to the amplitude of the carrier signal (Vc).

    m = Vm/Vc

    The modulation index determines the amount of modulation applied to the carrier signal. If the modulation index is too low, the modulated signal will not contain enough information from the modulating signal and will sound distorted. If the modulation index is too high, the modulation will exceed the limits of the carrier signal and result in overmodulation, causing distortion and interference.

    In an AM system, the modulation index is also related to the percentage of modulation (%m), which is defined as:

    %m = (Vm/Vc) x 100

    For a sinusoidal modulation signal, the maximum amplitude of the modulated signal is given by:

    Vmax = Vc(1 + m)

    and the minimum amplitude is given by:

    Vmin = Vc(1 - m)

    The amplitude of the modulated signal varies between these two values as the carrier signal is modulated by the modulating signal.

    In summary, the modulation index is a key parameter in an AM system that determines the level of modulation applied to the carrier signal. It is important to carefully adjust the modulation index to avoid distortion and achieve optimal signal quality.
