[edit] Naming Convention

There seem to be confusion about two main topics in digital design: 1) digital electronics which is CMOS level design and 2) digital logic which is logic level design. Digital electronics is basically analog design of digital systems where tools such as pspice and cadence are used for simulation and design. On the other hand, digital logic is logic level design where tools such as xilinx, VHDL, or FPGAs are used for simulation and design.

For instance, in digital electronics an inverter is built using one nMOS and one pMOS (pure analog). This inverter is then used in digital logic to construct a flip flop (pure logic).

[edit] Root page

I thought a Root page could not have any parents. Have you changed that idea now?--Light current 22:34, 27 February 2006 (UTC)

[edit] Relevence of link?

Would this link be worth adding, as this computer is discussed in the article (I found it Googling to find out what a Tinker Toy was)

[edit] Article move: digital circuit -> digital electronics

I moved this article from digital circuit to digital electronics to match the name of analogue electronics for the same of consistency. Previously, digital circuit was an article that was merged into (the former) digital electronics. That edit history is now at digital electronics/old. Cburnett 22:44, 3 December 2006 (UTC)

It is usually good to discuss proposed moves first. I'm not familiar with the history, but to me the term "digital electronics" refers to the market for products, such as phones, computers, alarm clocks, etc., rather than to the circuits and techniques that the article seems to be about. I think "digital circuit" was a better title for the existing content. In any case, you can't start with "A digital electronics is..." Dicklyon 04:18, 4 December 2006 (UTC)

Good to discuss first: perhaps. Then there's WP:BB. It made little sense to have analog electronics and digital circuits with analog circuits and digital electronics being redirects. It was inconsistent, so I moved it. I also just haven't gotten around to cleaning it up until just now. I'm not done, but it's a start. Cburnett 03:40, 7 December 2006 (UTC)

[edit] Digital electronics are the most common representation of Boolean algebra

i think this misleading because of fuzzy logic and tri-state. the traditional Boolean algebra is 2 valued.66.217.165.101 10:00, 2 August 2007 (UTC)

fuzzy and tri-state logic are not nearly so common as digital binary logic. Dicklyon 15:28, 2 August 2007 (UTC)

[edit] References vs. Sources vs. Referenced vs. Citation

I believe that this article should be tagged with {{Unreferenced}}.

However, from the article, Unreferenced, it is unclear to me whether this tag is appropriate because this article does contain references, but the references are not cited. (The template displays "This article does not cite any references or sources." [Emphasis added].)

I have started a discussion in Template_talk:Unreferenced to help clarify this issue.

Clearly, the references provided with this article do not support all of the statements in this article and it is unclear which statements they do support. So which template is appropriate?

Softtest123 15:55, 19 October 2007 (UTC)

I added the appropriate tags. Dicklyon 18:03, 19 October 2007 (UTC)

Thanks. I saw that. I'm wondering, however, if {{refimprove}} and {{citations}} actually cover the situation where there are no citations. My concern is also with the instructions for applying the {{Unreferenced}} and {{refimprove}} tags because of the wording of the template texts (referring to "citations"). I'll probably use the multiple tags that you applied in the future where there are references but no citations to those references. Seems to me there should be a single template for when there are no citations and it should be documented with the citation templates. Softtest123 18:58, 19 October 2007 (UTC)

[edit] Digital Electronics, Digital Systems, and Category

The article Digital Electronics is a redirect of Digital Systems; the category used for the article is Digital Systems. That category name is vague and had attracted, I think, subcategories that were never intended: Computing, Databases, Digital libraries, for example. Could someone familiar with this article add a summary to the Category page, indicating what kinds of topics would be appropriate subcategories? If that is done, I'd be happy to update the current subcategory entries. Thanks tooold 03:30, 5 November 2007 (UTC)

[edit] Digital Logic

Digital Logic redirects here, but it's very difficult to get any idea for what digital logic is from this article. If it's going to be a redirect, some sort of explanation seems necessary. The Jade Knight (talk) 06:36, 9 May 2008 (UTC)

What are the universal gates? —Preceding unsigned comment added by 58.68.126.229 (talk) 09:30, 6 August 2008 (UTC)

I am surprised by how many universal gates there are.

functional completeness lists the most popular universal gates.

Reversible Computing/3 input universal logic gates describes nearly 8000 more universal gates.

[edit] This article needs to be re-written by an expert in the field

This article contains things which are not directly relevant to digital logic, and many important details are missing, such as equations and graphs. I would re-write the article myself, but I'm too busy with work.ElectricalEngineer 6:47, 25 October 2008 —Preceding unsigned comment added by 24.242.203.168 (talk)

That's why it has been tagged as needing help, for over a year now. Feel free to pitch in if you find time; it's a daunting task, I agree. Dicklyon (talk) 04:53, 16 November 2008 (UTC)
