Andy,
FYI besides the KMethod, DePoli/Borin/Sarti et alias always in the 1990s also
formulated the W-method which was the dual of KMethod but using the wave
digital filter theory by Fettweis.
AFAIK is not so easily used because of the increased complexity of
nonlinearities adaptors involved (yo
Hi Andy,
thanks for your hint at this very interesting wikipedia article.
It is certainly correct, that those filter-realizations with a sample-delay in
the feedback-path are based on the "explicit" methods described in that article.
You are also right, that using an implicit approach does elimi

It's not pointless for marketing in the sense that instantaneous feedback is
much easier to explain than implicit integration. Users usually don't

At that time,we should offer real-time spice to let our dear customers tinker
with their virtual circuits. We’ll offer in-app purchases like “bumble bee
Agreed 100% Vadim. Only a human can detect the design principle, thus focusing
on the core points.
Moreover the engineer must also know why that gear is so good sounding and then
investigate on its history. I remember the fuzz face was very difficult to
produce because of the germanium transis
Oh yeah?

You just need to convince SPICE to leave out components connected to identical
nodes ….

I've been following this zdf discussion with some interest, though it is
unfortunately a bit over my head. I'll take a look at Vadim's book for starters
and see if that makes any sense. Any suggestions for learning the basics of
electronic circuits would also be welcome. > My concern is what wil
Hi Clemens and Urs!
Time for a backflip from me, I completely agree with all the points you
have both made in that describing to customers that there are no delays in
feedback paths is much easier than describing implicit integration schemes.

I must say that where I received my (at the time) top level education,
the PhD's had much higher standards concerning human modesty and
theoretical respect.
Probably that is because at the technical university one is supposed

Thanks to Clemens for spotting an error in the implementation of the skf,
it was a copy and paste error from the svf version where I didn't update

Also, speaking for myself, don't mistake my levity for irreverence.

Thanks very much Ross for taking the time to look at this! There is a lot
of reading and theory so until I get some more time I personally can't
really take on board any of it to provide you with any useful comments, but
I appreciate your time.
All the best,
Andy

But here is another backflip: How about this one, take a basic one pole
