Three Domains - FIR |
The connection between the Z-transform domain of poles and zeros
and the time domain, and also the frequency domain is illustrated
with several movies where individual zeros or zero pairs are moved
continuously.
|
 |
PeZ GUI |
PeZ (pezdemo) is a MATLAB tool for pole/zero manipulation.
Poles and zeros can be placed anywhere on a map of the
z-plane.
The corresponding time domain (n) and frequency
domain (ω) plots will be displayed.
When a zero pair (or pole pair) is dragged, the
impulse response and frequency response plots will
be updated in real time.

 |
PeZ Tutorial |
These movies describe how to use the PeZ graphical user interface
to place/move poles and zeros.
They also show how to display the associated impulse and frequency response.

Z to Freq |
A demo that illustrates the connection between the complex
Z-plane and the frequency response of a system. The frequency
response is obtained by evaluating H(z) on the unit circle
in the complex Z-plane.
