Hello, I've got a modulated signal - Y(f) (the question doesnt say if AM or DSB or whatever) which it's spectral modulted signal is shown(in the file i've uploaded).its is modulated by a carrier of sum of several COS. It asks what is the average energy or power( I should decide) of the modulated signal y(t)^2 - if W=100kHZ. I think that it is power signal. I've tried to do that with parseval:∫|Y(f)|df from and got 400KJoule. but I dont know wheter it right or wrong and I dont know how to do the Integral because it is not periodic. Thanks!
