Well, he did state that assumption, although what I understand is that the assumption that the average of the message is 0 means we will neglect the term avg{2A^2 k m(t)cos^2(wt)}. However,my question is if ∫ ab is not equal to ∫a ∫ b then how come average(ab) = average(a) average(b) Thanks !

so avg{s(t)^2} = avg{A^2 k^2 m(t)^2 cos^2(wt)} + avg{2A^2 k m(t)cos^2(wt)}+avg{A^2 cos^2(wt)} still who says avg{A^2 k^2 m(t)^2 cos^2(wt)} = avg{cos^2(wt)} * avg{A^2 k^2 m(t)}

Homework Statement Trying to calculate Conventional AM average transmitted power of the modulated signal s(t) = A (1+ka m(t) ) cos(2∏f t) where A: carrier amplitude ka: amplitude sensitivity m(t) : message signal f: Carrier frequency my professor's lecture notes calculate the average power as...
