Welcome to the Bode Plotter!
Graph the magnitude and phase of any system transfer function.
Just a simple web interface to Gnuplot.

Enter up to five system transfer functions:
An example (a low-pass inv. Chebychev) demonstrating syntax is shown. Note that pi is predefined and that ** can be used for exponentiation. Be sure to use an * to indicate multiplication, even between quantities in parentheses.
Specify the graph parameters:
Frequency Units
Frequency Range
Magnitude Range (dB)
Phase Range (degrees)
Hertz
radians/second
The syntax is min:max for each of the ranges. The min and max frequency values should be powers of 10.
