An amplitude modulated wave is as shown ...

An amplitude modulated wave is as shown in figure . Then , the modulation index will be

A

`0.20`

B

`0.50`

C

`0.67`

D

`0.8`

Text Solution

Verified by Experts

The correct Answer is:
C
`V_("max")=50V,V_("min")=20V`
`m_(a)=(V_("max")-V_("max"))/(V_("max")+V_("min"))=(50-20)/(50+20)=0.67`
