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 intex of 75 % ?

Text Solution

Verified by Experts

`mu` = modulation index
`= (A_m)/(A_c)`
`rArr A_m = mu xxA_c = 0.75xx 12`
`= 9 "volts"`.
