A sinusoidal voltage amplitude modulates another sinusoidal voltage of amplitude 2kV to result in two sidebands, each of amplitude 200V the modulation index is

A

0.2

B

0.3

C

0.4

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
A
Amplitude of each sideband `=(muA_(c))/(2)`
`therefore 200 V=(muxx2kV)/(2)=(muxx2000V)/(2)` or `mu=(2xx200)/(2000)=0.2`
