Control Systems
The input-output relationship of a linear time invariant continuous time system is given by r(t) = d²c(t)/dt² + 3 dc(t)/dt + 2 c(t) Where r(t) and c(t) are input and output respectively. What is the transfer function of the system equal to?

 2/(s² + 3s + 2)
 1/(s² + 3s + 2)
 2/(s² + s + 2)
 1/(s² + s + 2)
