4. Note: Try to enter the real and imaginary values within the range (-8,3) for better visuals of points in z-plane. If any point in z-plane is not visible means value of the point is out off the axis range.


5. Click on 'Plot' button to get the Pole-Zero map of S plane and Z plane. Plot can be downloaded by clicking on 'Download' button.


6. Click on 'Enter ζ , ω_n Values' dropdown button. Enter the values of damping ratio (ζ)and natural frequency (ω_n). Click on 'Run' button in the dropdown-menu to get the Pole Map of S plane and Z plane. Plot can be downloaded by clicking on 'Download' button.


7. Click on 'Clear' button before every new simulation to clear the previous map.


8. Note: Do not click on 'Clear' button if you want to enter values of multiple poles and zeros.
