(a) !lssurning zero initial conditions, find the transfer j1m.ction for a system. !.hot obeys the equation jj + 4y + 4y = u(t).

(b) Fmm the transfer function obtain the unit step response of the system.

(c) From the tmnsfer function obtain the impulse response of the system.

(d) Differentiate the answer to part

(a) and compare the result with the impulse Tesponse obtained in (c).
