A few historically relevant contributions to solving network equations, and
some related physical/mechanical excercises
Keep in mind when "simulating" linear, time-invariant electrical networks, that
it can be proven that the equations coming from the MNA method are the actual
differential equ

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

But Theo, music-dsp is not a university list. There is no reason at all
to expect/assume that anyone has any particular qualification, nor even
a "relevant" one. People are doing things here for love of the subject,
not for grade points. They like reading the discussions, even (or

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
to decent work, and pass, say, the sophomore year (of EE in my case)

See what happens when you start with the puns?
I just lost a good half hour trying to work out how Cauchy's Integral
Theorem follows from Green's Theorem in the Plane.
Because I wanted to make a pun using the word Green.
I'm so sorry.

In doing this, are you trying to compute the residue at the pole by using
the Cauchy integral formula?
Sorry, couldn't resist t

Hi,
I'm going to have a go at answering, but there will be points where I'm not
sure exactly what you're saying. I'll be as clear as possible and request
clarification.

Suppose we take a simple 1st order low-pass (or high-pass) filter in the
digital domain, and compare it with the corresponding electronic
implementation, preferably as a network theory example, ignoring
electro-magnetics, Johnson noise, and physical delay of currents through
wires, which are re
