Question

The modulation index of an A.M. wave having maximum and minimum peak to peak voltages of $14 mV$ and $6 mV$ respectively is: [JEE Main 2023, 29 Jan (Shift 2)]

YESPYQ · Accepted Answer

Correct answer: b) 0.4. $\begin{aligned} & \because \mu=\frac{A_{\max }-A_{\min }}{A_{\max }+A_{\min }} \ & \Rightarrow \mu=\frac{14-6}{14+6}=0.4\end{aligned}$

The modulation index of an A.M. wave having maximum and minimum peak to peak voltages of \(14 mV\) and \(6 mV\) respecti…
