Question

carrier wave of peak voltage 15v is used to transmitt a message signal find the peak voltage of the modulating signal in order to have a modulation index of 60% please answer quickly

Answer 1

$\beta = 0.6 \\ we \: know.. \beta = \frac{v}{z} k \: \: \: \:$
Where z = amplitude of carrier wave
V = amplitude of modulating wave and k is a dimension less constant.
So solving we get v = 0.6× 15 =9 V ans.
Hope this is ur required answer.
