A carrier wave of peak voltage 12 V is used to transmit a message signal . What should be the peak voltage of the modulating signal in order to have a modulation index of 75% ?

A

18 V

B

22 V

C

16 V

D

28 V

Text Solution

Verified by Experts

Modulation index `(mu) = (E_(m))/(E_( c))`
`rArr " " (3)/(4) = (E_(m))/(12)`
`rArr " " E_(m) = 9`
