E8.7 Consider a system with a closed-loop transfer function

100 G(s) (s+2s+16)(s2+s+64)* This system will have a steady-state error for a step input. (a) Plot the frequency response, noting the two peaks in the magnitude response. (b) Predict the time response to a step input, noting that the system has four poles and cannot be represented as a dominant second-order system. (c) Plot the step response.
