Hello Andrew.Yes as I already said I know the Mitra paper of the 75 but it
relates to linear networks. Of course I know the Italian guys (personally) and
to my knowledge they were the pioneers as far as the nonlinear systems are
concerned. I thought that there were references in the 70s t
Hi Andy,
Also, the purpose of a "reflection-free port" in wave digital filters
(WDF) was to eliminate delay-free loops. That probably goes back
earlier than 1975 since WDFs started in 1969.

An important early reference is:
Szczupak, J. and Mitra, S.K., “Detection, Lo
Unless you consider the papers by Mitra et alias, but dealing only with linear
graphs computability…which are dated effectively in the 70s.

Okay, a few more thoughts:

That's only true *if* it's a non-dithered converter (read: a converter
