Instructions

1. At first enter the desired value of sampling time. Here default value is 1 sec for sampling time.


2. Click on 'Select Entry Method' dropdown button and select the available options to enter the values.


3. For Pole - Zero entry: click on 'Add Poles' button to enter the pole values and click on 'Add Zeros' button to enter the zero values. Click 'Add Pole' or/and 'Add Zero' buttons multiple times to enter multiple pole/zero values.


4. Note: For better visualization of points in the S-plane and Z-plane, try selecting real values between -10 and 2.71, and imaginary values between -10 and 10 (excluding the endpoints). If any point in the S-plane or Z-plane is not visible, it means the value of the point is outside 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.
9. Note: To zoom into a specific region of the Z plane map, press and hold the left mouse button, drag to select an area, and release the button to apply the zoom.
