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% ?

Text Solution

Verified by Experts

(i) Appropriate size of the antenna or aerial.
(ii) Effective power radiated by an antenna
(iii) To avoid mixing up of signals from different transmitters .
Modulation Index
`mu=(a_m)/( a_c)`
`:. 0.75=(a_m)/(12)`
` implies a_m=9V`
