A wave is modulated by two sin waves having modulation indices of 0.3 and 0.5. Find the total modulation index? a) 0.1 b) 0.7 c) 0.58 d) 0.35 |

Answer» c) 0.58 Given that m1 = 0.3 and m2 = 0.5. Total modulation index will be equal to \(\sqrt{m_1^2+m_2^2}\). By substituting values we have \((\sqrt{0.3^2+0.5^2)}\) which is equal to 0.58. |
