Consider an LTI system with magnitude response
and phase response arg{H(f)}=-2f. If the input to the system is
x(t)=8cos(20πt+π/4)+16sin(40πt+π/8)+24cos(80πt+π/16),
then the average power of the output signal y(t) is
x(t)=8cos(20πt+π/4)+16sin(40πt+π/8)+24cos(80πt+π/16),
then the average power of the output signal y(t) is
Correct : 8
