(D) The modulation index $\mu$ is defined as the ratio of the difference of maximum and minimum amplitudes to the sum of maximum and minimum amplitudes.$\mu = \frac{V_{\max} - V_{\min}}{V_{\max} + V_{\min}}$Given $V_{\max} = 6\,V$ and $V_{\min} = 2\,V$.Substituting the values:$\mu = \frac{6 - 2}{6 + 2} = \frac{4}{8} = 0.5$To express this as a percentage:$	ext{Modulation index} = 0.5 	imes 100\% = 50\%$.

In $AM$ modulation,a signal is modulated on a carrier wave such that maximum and minimum amplitude are found to be $6\,V$ and $2\,V$ respectively. The modulation index is $\dots \%$.
