About Bode & Nyquist
This application allows you to plot the Bode and Nyquist diagram of a transfer function.
The transfer function is entered via a simple numeric keypad and has been specially adapted to make immediately available all the keys you need.
Open Loop Transfer function or the Closed Loop Transfer can be entered separately.
The app automatically evaluate system stability.
The number of unstable closed-loop poles, the number of unstable open-loop poles and the number of clock-wise encirclements of point -1+j0 are shown together with the Nyquist Plot.
Gain and Phase margin are shown together with the Bode Plot.
For each graph the following gestures are supported:
* Drag: To move the chart in the desired position;
* Pinch: To enlarge or shrinks the graph;
* Double Tap to restore the position and zoom level of the graph to their original values.
Through a dedicated function you can set the maximum frequency of the Nyquist diagram and the frequency range for the Bode diagrams of the module and phase.
There is also a complete online help.
BEFORE LEAVING AN ANONYMOUS NEGATIVE FEEDBACK AND THROW AWAY YOUR MONEY:
1) READ THE MANUAL AGAIN;
2) CHECK AGAIN THE SYNTAX OF THE ENTERED FUNCTION;
3) CONTACT ME, AND I WILL DO MY VERY BEST TO HELP YOU.
