When a sinusoidal carrier wave of voltage amplitude 3 kV is amplitude modulated by a sinusoidal signal voltage, two side bands each of amplitude 600 V are produced. What is the modulation index ?

A

a. 0.25

B

b. 0.3

C

c. 0.35

D

d. 0.4

Text Solution

Verified by Experts

The correct Answer is:
D
Amplitude of each side band =`(muA_C)/2`
`therefore 600=(mu xx 3xx1000)/2`
`therefore mu=1200/3000=4/10`=0.4
