This is due to the constant in the transfer function.

A given transfer function may be realized in many ways.

An example program using the transfer function might look like this:

Given a transfer function in the same form as above:

Example of a transfer function is provided Figure 2.

The straight line joining these two point is the transfer function of the network.

Past this point the transfer function will again be linear but with a different slope.

This results in each having a different transfer function.

Two different transfer functions are of interest to the designer.

Suppose now that s is replaced by in the transfer function.
