message: I'd like to put back to old picture of the smith chart. the current one does not have enough numbers to be useful. Does anyone oppose reverting back to the old one?

:I would like to see the old one. At the very least any diagram of a Smith Chart will do. A picture tells a thousand words. Piercetp 01:56, 20 April 2006 (UTC)

thread_title:  Picture 

message: I have added quite a bit plus some examples. I hope everything is relevant but there may be some repetition to tidy up. I think it could benefit some constant gain/NF circles and even some screen dumps from actual VNA measurements. I just can't get the equations visually consistent for some reason, they come out in all shapes and sizes and sometimes with little tags on the ends, I will study the math help a bit more and improve if nobody else does. 
Also the following might be useful additions
Examples of Test Results Displayed on Smith Chart Formats
Smith Charts region greater than unity (amplifier stability etc.)
Noise Figure Circles, constant gain circles

thread_title:  Substantial Additions 

message: Just a few points:
*Headings should only have the first word capitalized (unless there is a proper noun of course). See WP:MOS
*The lead section could perhaps be expanded to two paragraphs per WP:LEAD.
*Don't have wikilinks in titles. (WP:MOS again :))
*A lot more references are needed for criterion 2b.
And also:
*Try to enforce the math either being in png format for consistency. (\, at the end of each <math> should be what's needed). It makes it nicer to read really.
*Some of those redlinks might actually be mistyped wikilinks to other pages.
Otherwise it's a good article, although technical! CloudNine 22:15, 30 October 2006 (UTC)

message: Mathematically speaking, the transform
z\mapsto \frac{z-1}{z+1}
as applied in the Smith chart is a special case of a Möbius Transformation. There should be a reference somewhere.

message: I have just added lots of 'force .png' tags to the TeX markup and they are more consistent at least. Also some improvements in the text flow, removal of excessive words etc.ChrisAngove 12:33, 25 December 2006 (UTC)

message: #distributed component = distributed element = is discussed in distributed element model?
#The Smith Chart is used with one frequency at a time so the temporal part of the phase (\exp(\omega t)\,) is fixed.[...] Why not \exp(j \omega t)\,?
#As someone seeing the Smith chart the first time, it was quite hard to figure out where these points and regions are: center of the Smith chart (z_T = 1 \pm j0\,), z_T = \infty \pm j\infty\, and the unitary circumference circle. 
Thank you for any help. --Abdull (talk) 11:29, 10 December 2007 (UTC)

message: Has anyone ever noticed that the lines you draw on a Smith Chart seem to consistently conform to Imperial units: inches and grains?!
I presume it's because Americans like using English traditional units in electronics as well.
I just wondered whether this was by design or just a coincidence.  —Preceding unsigned comment added by 144.32.126.12 (talk) 15:13, 1 May 2008 (UTC)
replies: text: you are partially correct : Americans use imperial measurements for the physical sizes of electronics components ( eg 0805 sizes of surface mount components ) which often became default standards. but I have never heard of imperial units for capacitance, inductance, impedance etc which are all derived from the SI system of units. for some reason the values of capacitors and inductors are not spaced linealy, but this is simply tradition now. the lines on the smith chart seem ok to, if you start from unit impedance values and work backwards. other wise I am not sure I undertsand what you are talking about. 86.32.232.35 (talk) 17:24, 17 August 2009 (UTC)

message: What is a "generic rectangular complex number"? Nijdam (talk) 18:01, 26 July 2012 (UTC)
replies: text: I suppose it means the complex numbers are expressed in rectangular co-ordinates, as opposed to the \scriptstyle re^{i\theta} polar coordinate form.  The generic bit refers to representation by generalised variables as opposed to a specific frequency function.  The phrase is probably a little redudant. SpinningSpark 17:24, 31 July 2012 (UTC)
