Bode and Nyquist Plots

The system or transfer function determines the frequency response of a system, which can be visualized using Bode Plots and Nyquist Plots. The pole/zero diagram determines the gross structure of the transfer function.

    These interactive tools are so good that learning and understanding things have become so easy. Thank you so much for developing such a tool and make it available for free for everyone. This kind of things really helps students like me.

    My query is that by any chance is it possible to use this tool offline (without connecting to the internet) or is there any offline version of these tools or any android apps. Can you kindly provide me with the information regarding this????

    I'm glad you find them useful, Ganesh. There is a plan to allow a download of a zip file of the entire collection. Stay tuned.

    The tool is awsome!! Very useful and FREE!! The only thing is that you can't write your own formula to calculate the diagrams; you have to try to set poles and zeros the more precisely you can to obtain the formula. Thanks anyway!

    Glad you like it, Gmark!
    The Mathlets are designed as teaching and learning tools, not for calculation. The ability to move the zeros and poles on the screen and observe the effects on the plots trumped any thought of inputting coordinates. But did you notice the zoom feature? You can achieve greater accuracy using it.
