The following operators are available for use. An operator's output is automatically assigned to an output function. The function's waveform is not displayed unless you drag a function color icon onto the function's output. After placing the 4th Order Bessel, Butterworth, Brickwall, or Gaussian operators, click on them to setup their cutoff frequency or other settings, if available. You also setup the Interpolation and Linear Equalizer operators by clicking on them.

The one-input and two-input User operators allow you to create custom operators using MATLAB or Python scripts.
