Marks: +1, -0

Consider an LTI system with magnitude response

|H(f)|={\{\table 1-\;{{|f|}}/{20}, , {|f|} ≤ 20 ; 0, , {|f|}>20}.

and phase response arg {H(f)} = -2f.
If the input to the system is

x (t) = 8\cos ⁡ (20π t + \;{π\;}/{4}) + 16 sin \;⁡ (40π t + \;{π\;}/{8}) + 24\cos ⁡ (80π t + \;{π\;}/{16}) .

Then the average power of the output signal y(t) is ____________.
