8.1 INTRODUCTION
Poles and Zeros of a Transfer Function
Poles: The poles of a transfer function are those values of s for which the function is undefined
(becomes infinite).
Zeros: The zeros of a transfer function are those values of s for which the function is zero.
Example of the Effect of Pole/Zero Locations
Figure 8-1.
From the development summarized above, the following conclusions can be drawn:

A pole of the input function generates the form of the forced response. (i.e., the pole at
the origin generates a step function at the output)
A pole of the transfer function generates the form of the natural response (i.e., the pole at -
