In the example shown below, the transfer function for a simple first order low pass filter is
used. Only the numerator and denominator constants A0 and B0 are required in this case.
These are equal to two pi times the cutoff frequency (first pole).
The cursor on the Bode Plotter may be used to confirm first order performance with -3dB at
10kHz. and rolloff of 6dB per octave above 20kHz.
