Question
Which of the following statement/statements about amplitude modulation is/are true? A The total power (Pt) in an AM signal is expressed as (P B C D P₁ = Pc+ ma 2 The modulation index is given as Ac Am When more than one sinusoids with different amplitudes are used to amplitude modulate a carrier, the overall modulation index for AM is- m₁ = √ (m², + m² ₂ + m² 3 + ...) 1 When ma = 1, only of the total power is in the sidebands and 3 2 remaining is in the carrier. 3 Submit
