E8.10 The dynamic analyzer shown in Figure E8.10(a)

can be used to display the frequency response of a system. Also shown is the signal analyzer used to measure the mechanical vibration in the cockpit of an automobile. Figure E8.10

(b) shows the actual frequency response of a system. Estimate the poles and zeros of the device. Note X = 1.37 kHz at the first cursor, and X = 1.257 kHz to the second cursor.
