.
The frequency response and step response plots of the system are shown.
Find two discrete-time approximants
H
(
z
) to the given transfer function using the bilinear
transformation, one with
T
1 and the other with
T
0.1.
For each of the two approximants, make a plot of
(a) the poles and zeros,
(b) the frequency response, and
(c) the step response.
