 A carrier wave of peak voltage 20 V is used to transmit a message signal. For getting a modulation index of `60%`, the peak voltage of the modulating signal is 

A

6 V

B

8V

C

12 V

D

33.3 V

Text Solution

Verified by Experts

The correct Answer is:
C
Modulation index,
`m=("Peak value of m(t)")/(A)=(M)/(A)`
`:." "M=mA`
`=20xx60%=20xx(60)/(100)=12V`
