A message signal of 1 KHz and peak voltage 50 v is used to modulate a carrier wave of frequency 1200 KHz and peak voltage 80 V. What is the modulation index ?

A

a. 0.5

B

b. 0.55

C

c. 0.6

D

d. 0.625

Text Solution

Verified by Experts

The correct Answer is:
D
`A_m`=50 V and `A_c` = 80 V
Modulation index or factor `(mu)` is given by `mu=A_m/A_c=50/80` =0.625
