The way I do it is to use gnetlist (or lepton-netlist) -g mathematica to =
make circuit equations in Mathematica. The function transferFunction =
from gEDAmath.nb solves them for the transfer function. I use =
Mathematica=E2=80=99s StateSpaceModel function, generally together with =
ToDiscreteTimeModel, to finish the job
Unfortunately, gEDAmath.nb was never in the gEDA distribution, so my =
(defunct) corporate website was the source. I should make this into a =
github project, but until I do, I can send you the file if you want it.
