* Generated by LTspice 26.0.1 for Windows.
* Bessel-Thompson Lowpass\nMaximally flat delay
* Trise =4.4*RC of any section
* Gaussian Lowpass\nZero overshoot step response.
* Chebychev Lowpass\nEqual ripple pass band.
* Elliptic Lowpass
* Butterworth Lowpass\nFlat freq response
* Fo is the 3db freq of the filters and\nscales the L's and C's to produce that\nresponse. The actual values can be\nviewed in the spice netlist.
* The RC filter gives a realistic bandwidth limited\ninput signal. Set the desired risetime in the .param\nstatement.
