A modulated carrier wave has minimum and minimum amplitudes of 900 m V and 300 mV respectively. What is the percentage modulation index ?

A

0.4

B

0.45

C

0.5

D

0.6

Text Solution

Verified by Experts

The correct Answer is:
C
`A_"max"`=900 mV , `A_"min"`=300 mV
`therefore mu=(A_"max"-A_"min")/(A_"max"+A_"min")xx100`
`=(900-300)/(900+300)=600/1200`=50%
