Vedclass · Answer

(D) The modulation index $(m_a)$ is defined as the ratio of the amplitude of the modulating signal to the amplitude of the carrier signal.For an under-modulated wave,$m_a For a critically modulated wave,$m_a = 1$.For an over-modulated wave,the amplitude of the modulating signal is greater than the amplitude of the carrier signal,which results in $m_a > 1$.Therefore,the correct option is $D$.
