I need help with this

A signal S (t ) is corrupted by additive noise /(t ) and then filtered. The output of the filter is denoted as Y(t). filter S(t) H(f) Y(t) N(t) The filter response is H(f) H ( f) = 12, - 5Sf s5 10, else 5 Assume that S(t ) and /(t ) are independent of each other and that they are wide- sense stationary random processes with zero-means and PSD functions: Ss( 1)=19-151 -95f59 0, else Ss(f) SN(f) =3, for all f SN(D) a) Find the power of the noise process { N (t)} b) Find the power in the output signal { Y (t)} c) How much of the power in { Y(t )} is due to noise
