P13.5 For the system in Problem P13.4, let r(t) be a unit step input and calculate the response of the system by synthetic division for five time steps.

Data from in P13.4 A closed-loop system has a hold circuit and process as shown in Figure E13.10. Determine G(z)

when T = 0.5 s and

Gp(s) = 3 s+3
