Bode Plot GeneratorDescription| How it works| Filter Analysis| Ziegler Nichols Tuning
This app will generate the Bode Plot given a transfer function of the form (a + bs) e-ts / (g + hs). (For generating the Bode plot for a system of a higher order, see Bode plot using Complex functions).

How to useThe use of this app is quite straightforward, simply key in the values of a, b, g, h and t into the cells B6 through B10. Key in the frequency range into the cells B13 and B14. Note that the units of frequency is rad/time. The Bode plot is generated.
Lets say we wish to obtain the Bode plot of (1 + 0.2s)/(1 + 2s), from 0.01 rad/s to 100 rad/s. We have
a = 1,
b = 0.2,
h = 2 and
t = 0.
Key in these values and the range. If done correctly, you should see the screen below.
