1. The problem statement, all variables and given/known data 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 0.5 A2( 1+< ka2 m2(t)>) where <.> is the time average. 2. Relevant equations Average Power (for periodic Signals) = 1/T (∫0T x2(t) dt) 3. The attempt at a solution average power for cos(2∏ft) =0.5 but applying the Average power rule I can't get this integral to be equal to the formula my professor's got! Thanks in advance.
