If modulation index of an AM wave is increased from 1.5 to 2, then the transitted power ________(a) remains same(b) increases by 20%(c) increases by 41%(d) increases by 50%I have been asked this question in exam.My question is from Problems of AM in portion Amplitude Modulation of Analog Communications |

Answer» RIGHT CHOICE is (c) INCREASES by 41% To explain I would say: When m=1.5, transmitted power . = 0.41 X 100 = 41% Therefore,there is an increase in total power by 41%. |
