The outline on the frontpage is tentative. I want to look at some reference resources to see if there is a better order for some of the information, and I want to look and see if there are more topics that should be covered in this book, before i start laying down chapters. --Whiteknight 23:29, 16 October 2005 (UTC)

I've set up this book to use the "Forward Slash" naming convention. --Whiteknight 17:32, 17 October 2005 (UTC)

I've created a few templates for use in this book:

[edit] What this book is not

Like with the other EE books, i am going to list here what i think the scope of this book should be, although this is certainly not set in stone.

  1. This is not a math book. We are not here to teach math, that is the job of the Math bookshelf. We cannot, however limit this book to the tools that are provided in math books because most math books do not give any coverage (at least no adequate coverage) to the Fourier, Laplace, or Z Transforms. We can introduce what we need here, but there is no sense rewriting what other people have already written.
  2. This book has a clear focus. The Circuit Theory and the Circuit Theory 2 wikibook cover basic hardware topics, and in a sense this book will cover the "software". This book will examine signals, and will demonstrate techniques for analyzing signals. Also, this book will consider hardware topics, but we are past the stage where we need to be diagramming the locations of individual circuit components.
  3. This book has a clear scope. Like any wikibook, it is counter-productive to include more information in this book then logically belongs here. By making the EE bookshelf highly modular, we allow for people who are taking divergent learning paths (Electrical Engineers versus Computer Engineers, Electromechanical Engineers, Automotive Engineers, or Biomedical Engineers) To read on the topics that interest them, without loading the reader down with excess baggage. This book should be limited to studies of signals, Fourier analysis, Z-transform analysis, and an introduction to basic filters. More advanced topics can be saved for another wikibook.
  4. This book should have lots of pictures. A study of electric signals is best facilitated by having lots and lots of pictures. In a sense, this is the trade-off: less math, and more graphs.

I've outlined on my user page a basic EE "curriculum" that i think forms a very natural progression of EE-based learning, while at the same time allowing people to diverge into different "specialties" as their interest dictates. --Whiteknight 22:15, 17 October 2005 (UTC)

[edit] need some diagrams

I feel like i've written up skeletons of all the pages that i can without supporting images. The remainder of the chapters in this book will be heavily graphical, by necessity. --Whiteknight TCE 02:50, 20 October 2005 (UTC)


[edit] Stability, transient performance

Since this book is also about Systems, shouldn't it have some sections about system stability and transient response? And perhaps things like negative feedback, root locus diagrams, and other useful things (I'm currently taking a class in Control Systems so I'm no expert on the subject, just trying to give some suggestions - what I've mentioned is all we've learned so far) --Gautamraj Sun Nov 6 08:35:01 UTC 2005

I would like to write a book about all those subjects, because i also have taken a number of control classes (classical controls, modern controls, digital controls). However, i feel like the addition of all those subjects into this book would cause this book to grow far too large, and lose way too much focus. Instead, i am preparing an outline of a future book that will encompass many different types of electrical control systems. you can find the outline for this book at Control Systems. Let me know if you have any suggestions about that book, but i probably won't put it into active duty for a long while now (until i can better expand it). --Whiteknight TCE 19:19, 5 November 2005 (UTC)
The outline mentioned above has been put on a bookshelf at Control Systems --Whiteknight (talk) (current) 22:24, 25 April 2006 (UTC)

[edit] Electrical Engineering, Basic signals

That book was merged into Signals and Systems at 19:25, 9 December 2005 (UTC). The primary contributer was User:WarrenWilkinson. Here is the contents of the talk page to that book:

To others who would wish to help author this wikibook, I recommend we keep detailed deriviations and proofs and advanged applications of things like the Forier Transforms, forier series, Laplace transforms and convolution in seperate eBooks and link to them in the prerequisites. That way this very advanced information can be centralized for all wikibooks to link too. In this book we should cover the application and usuage of these things, and link to more advanced texts that prove these theroums.

[edit] title of book

maybe this should just be called introduction to signal processing? - Omegatron 15:38, 22 Oct 2004 (UTC)

I think that's a bit narrow. This book already has a section on filters (which are systems), and I would like to cover more systems eventually here as well. --Whiteknight (talk) (current) 21:34, 3 May 2006 (UTC)

[edit] Spelling and zeroes

Good work to the person who started compiling this book. I however, recommend that someone needs to go through and check the spelling properly. I am just about to go through and fix some of the spelling mistakes I've seen, and take out some of the rubbish that people have edited in: Example, string of zeros.
I'm considering seriously contributing to this book, and I'll try to stick to the recommended guideline of linking detailed proofs.
Although, if the text does become more comprensive at some stage, adding them might be cool, as long as they are clearly seperate from the more concise statements and applications.

[edit] New Sections

I would like to start adding new sections to this book, because it is currently very small and could handle new information. I would like to include more information about the frequency-domain, and I would like to add a section on digital domain (z-transform introduction, digital filters by poles and zeros, etc). If anybody else can think of other subjects that would go well in this book, write about them here. --Whiteknight(talk) (projects) 14:52, 10 May 2006 (UTC)

I also want to add more information about Bode plots here. --Whiteknight (talk) (projects) 00:08, 28 August 2006 (UTC)
