Question

Direct Synthesis of Band-Pass Transmission Line Structures

Author: Carlin, H.J. ; Kohler, W.

Realizable band-pass (zero of transmission, i.e., infinite loss, at dc) equiripple gain functions are constructed which permit exact physical realization of systems consisting of cascaded lines and stubs. The problem of the realization of a prescribed load resistance is solved when a dc zero of transmission is present due to a shunt short-circuiting stub. The exact limits of realizable load resistance are given for equiripple band-pass gain functions and a straight-forward method is presented to synthesize any desired value of load between the predetermined limits. The basis of the synthesis technique is the choice of location of the shunt stub in the cascaded chain.

The Nuhertz guy now has a transmission-line filter design program.  We have his LC design program, and it's dynamite. It can do in minutes what would take weeks to do by hand. --  John Larkin         Highland Technology, Inc picosecond timing   precision measurement  jlarkin att highlandtechnology dott com

How could that possibly be as useful as a 50 year old paper?

John Larkin · Answer

Maybe because it could design a filter in a few minutes. Even LC filter prototype tables, like in Williams, are computer generated. Past a couple of elements, filters are essentially impossible to design analytically. --  John Larkin         Highland Technology, Inc picosecond timing   laser drivers and controllers jlarkin att highlandtechnology dott com

Why is Bloggs so ignorant? Some of the old papers are the best... instead of solving math with a computer, they actually manually do the math, revealing many opportunities... in my case, behavioral modeling techniques. 		                                         ...Jim Thompson --  | James E.Thompson                                 |    mens     | | Analog Innovations                               |     et      | | Analog/Mixed-Signal ASIC's and Discrete Systems  |    manus    | | San Tan Valley, AZ 85142     Skype: skypeanalog  |             | | Voice:(480)460-2350  Fax: Available upon request |  Brass Rat  | | E-mail Icon at  |    1962     |               I love to cook with wine.

snip  So,you really are clueless as to how well we were getting knowledge of  electronics dialed in back then.   The subsequent computer programs are based on the same knowledge, dork.

Simon S Aysdie · Answer

Depends on what you mean. The realization is completely analytical if done according to the "insertion loss method." (And these days, this is usually the case.) Post realization manipulation can also be completely analytical . Finding an "optimal" approximation function based on a mask, to then be r ealized, is an optimization problem.

Just because these details are hidden from the user by the filter program d oes not take away what they are.
