1. For a 2nd order system with a single zero transfer function U(s)Y(s)=(4s+1)(s+1)2(14s) Assuming a unit step change in the input at time t=0;U(s)=1/s (a)What is the final value of the output? (b) Find y(t)=?(c) What is the minimal value of output response and occur at what time? Heaviside expansion can be used for partial fractions of Laplace form for inversion. 1+1231e1/1+2132e1/2s(1s+1)(2s+1)3s+1
