If a wave is modulated by two waves. One of them has modulation index

1.	If a wave is modulated by two waves. One of them has modulation index equal to 0.75 and other has 0.2, the total modulation index will be ________(a) 0.67(b) 0.58(c) 0.77(d) 0.35I have been asked this question in a national level competition.Asked question is from Power Calculation topic in division Amplitude Modulation of Analog Communications
Answer» The correct OPTION is (c) 0.77 Explanation: GIVEN that m1 = 0.75 and M2 = 0.2. Total MODULATION index will be equal toBy SUBSTITUTING values we havewhich is equal to 0.77.
