 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

6V

B

8V

C

12 V

D

33.3 V

Text Solution

Verified by Experts

The correct Answer is:
C
`mu = (A_m)/(A_c)`
`rArr 60% = (A_m)/(20)`
`therefore A_m = 12V`
