Modulation index =( text Amplitude of mod ulating signal / text Amplitude of carrier wave ) μ=(1/2)

Q. A modulating signal is a square wave, as shown in the figure.

If the carrier wave is given as $c (t) = 2 sin (8 π t)$ volts, the modulation index is:

$\frac{1}{3}$

1

$\frac{1}{2}$

$\frac{1}{4}$

Modulation index
$= \frac{Amplitude of mod ulating signal}{Amplitude of carrier wave}$
$μ = \frac{1}{2}$
