Maybe ya''ll have seen this; I thought it was interesting:
Also:
These popped up on some synthesis searches.

Nice, thanks.
I have copies of: black & fosters papers, cauer & bodes books. these were some seriously clever buggers.
Cheers Terry
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. : : : Other amusing stuff:
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
MIT:
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)
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.
