For system shown knowing that h1(t) is a derivative operation The output of h1 is the derivative of its inout and h2 is time shifting poeration ' the output its delayed by 2 second relative to its input Vin(t) - r(1) 2 r(t-1) + r(t-2) Vin(t) hl(t) h2(1) Vo(t) Find: 1- The Total energy in input sigansl 2- Over all transfer function 3- Vo(t)
