Hello, Does anyone know of any way to generate a continued fraction from a Filter Model? Thanks.

Oh. Ok. Sorry. Yes. I guess it's there.

I'm looking at your other links and I'm not seeing it there either.

I'm looking at your first link and I'm not seeing it.

The first one in Properties & Relations [link]

Other occurrences can be found elsewhere as well [link] [link]

I was not able to find it in documentation either (I asked Suba to weigh in for that reason).

Thanks Suba! That saved me a boat load of work. Where in the documentation does it say that?

If you are looking for the underlying expression you can do the following:

BesselFilterModel[3][ss][[1,1]]

and get

15./(15. + 26.335085835*ss + 18.494313224981806*ss^2 + 
   5.4116591804363505*ss^3)

Please add an explicit example in Mathematica.
