Problem 2: Oh no! Someone has mixed up the data files for a set of 4 experiments. A unit voltage step was given to each of the following systems: 5 1 Ga Gb s2 +0.6s+1 s2 +0.6s+1 36 1 GC = Ga = s 24s+36 s + 5s +1 After plotting the data, you obtain the figures shown on the next page. 1. Match the transfer functions to the appropriate plots. 2. For each transfer function explain how you reached your conclusion regarding the correct plot.
