Communication System Question 1
Question 1 - 24 January - Shift 1
A modulating signal is a square wave, as shown in the figure.
If the carrier wave is given as $c(t)=2 \sin (8 \pi t)$ volts, the modulation index is :
(1) $1 / 4$
(2) 1
(3) $1 / 3$
(4) $1 / 2$
Show Answer
Answer: (4)
Solution:
Formula: Modulation Index
Modulation index
Amplitude of modulating signal
$=$ Amplitude of carrier wave
$\mu=\frac{1}{2}$
