Nice, thanks.

I have copies of: black & fosters papers, cauer & bodes books. these
were some seriously clever buggers.

Cheers

I've always liked the whole synthesis topic. I think I was searching
for the Foster or Darlington paper when I stumbled on these articles.

Do you have a electronic copies of those Bode and Foster papers? I
wouldn't mind having them...

The Otto Brune paper is here:

I can't bring myself to pay for a printable version.

Interesting!

Since I'm an MIT alumnus I tried to find how to sign up.

But that set of pages is about as obtuse as they come :-(

I'll see who I know at MIT who is still alive ;-) and ask how to do
it.

Cool.

Hey, did you ever take any classes w/ Guillemin's being the
instructor? He gets referenced all over the place on network & filter
synthesis books/papers. I have three of his books, although I don't
have time to go through them.

I was surprised they keep this stuff too, but the Brune synthesis and
"positive real functions as physically realizable" is famous in the
synthesis cult. laughs

if I ever get any spare time (running around like headless chicken at
the moment) I can scan Fosters paper; email me off-line (Im sure you can
figure out my email addy) and I'll send you the scans. Bodes book is
about 700 pages perhaps you means Blacks paper

Guillemin was notorious for his simplistic approach to passives... 1
Ohm, 1 Henry, 1 Farad kind of stuff... not very useful for calibration
into the real world.

But I was in Course 6B... honors EE, so I had Harry B. Lee, 1959-1960.
He was super! I will forever be indebted to his insight into loop and
nodal analysis... I'm still a whiz kid at it ;-)

What I got a cackle out of was the thesis advisors: V. Bush, E.A.
Guillemin, and N. Wiener, with indebtedness to W. Cauer ;-)

Good stuff! Thanks for posting.

Well alright. Maybe he was a leftist weenie, anyway. Poles are on
the left, I know that much; zeros can be found everywhere.

I don't see anything wrong with the number 1. All the background work
in analog filter synthesis is R=1, w=1, and via a LP prototype.
Everyone does it that way ,(normalized & LP) and then simply transform/
scale it.

Just cuz you hate small integers, your torture test is to synthesize
the simple impedance:

Z(s) = (s*(s + 1/2))/(s^2 + 1/6)

But I was in Course 6B... honors EE, so I had Harry B. Lee, 1959-1960.
He was super! I will forever be indebted to his insight into loop and
nodal analysis... I'm still a whiz kid at it ;-)

I wonder if that is the same Lee that did the statistical comm theory
stuff. I think there was a Lee at MIT right about that time.

I was thinking about getting this:

Yeah, it is a who's who list. I wonder if he got a good job after
graduation. Guillemin dedicated _Synthesis of Passive Networks_ to
Brune.
