A 100 V carrier wave is mode to vary betqeen 160 and 40 V by a modulating signal . What is the modulation index ?

A

0.6

B

0.5

C

0.4

D

0.3

Text Solution

Verified by Experts

The correct Answer is:
A
`A_("camier")"wave"=100`
`A_(e)+A_(m)=160`
`A_(c)-A_(m)=40 rArr A_(m)=60`
`mu =(A_m)/(A_e)=60` .
