If 3 A Random Process Has Power Density Spectrum Sy F Cos 2 Bo If I Bo O Otherwi

This is a communication theory problem.

Can you show the steps clearly? Thank you

If3 ) A random process * ( + ) has power density spectrum , SY ( f ) =COS2 BOIf I BOO ,otherwiseWe pass the random process through a low- pass filter having frequency response ,H ( F ) = }| 1, If KBp10 , otherwise, to produce a random process , * ( + ) .a ) Find and sketch ( precise labels ! ) the power density spectrum of * ( + ) , whenB = BO 1 2 .b ) Find Var ( Y ( t ) as a function of By .
