Talk:Analog circuit

Merge into Analog electronics

It has been suggested that the Analog circuit and Analog Electronics articles be merged. I concur, for the simple reason that nearly all analog electronics is based on charge flowing through circuits. The only exceptions that comes to mind are (1)electret microphones, which rely on a permanent electrical charge on the diaphram of the microphone, and (2) many semiconductor memories that retain information when power is removed by injecting charge into selected parts of the memory (ie. EEPROMS).

I also take issue with the statement near the beginning of both articles "The word "analog" implies an analogy between cause and effect, voltage in and voltage out, current in and current out, sound in and sound out." I believe the analogy is between a measurable phenomenon in the world outside the electronic system (e.g. sound, light, mass, temperature) and an electrical signal within the electronic system. For example, an analogy might be created such that 0 volts on a certain pin of a temperature measuring integrated circuit represents 0 degrees Celsius, 1 volt represents 100 degrees Celsius, and between these limits voltage is proportional to temperature.Gerry Ashton 18:37, 22 May 2006 (UTC)

I agree. The articles deal with the same thing. I would also suggest that Analog signal be merged too. Alf Boggis 11:24, 21 September 2006 (UTC)

I definitely agree. Analog circuits must be in analog electronics. Some links to related laws and transistors should also be given. This is the only reliable web source for me while writing reports...

Origin

The concept of analog is that the signal is similar to itself as time progresses as opposed to digital in which the difference in signal is distinct Hackwrench 08:06, 1 July 2006 (UTC)

No. All currents and voltages are analogs of the input or out put signal. Thats all!--Light current 15:41, 1 July 2006 (UTC)

An analog or analogue signal is any variable signal continuous in both time and amplitude. It differs from a digital signal in that small fluctuations in the signal are meaningful. Analog is usually thought of in an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

Why are you (still) discussing on it?--Doktor Who 16:20, 1 July 2006 (UTC)

Redundancy

I may be mistaken, but it seems to me that a rather substantial portion of the text is just a slight rewording of another block of the text. Specifically it seems that most of the text was copied from "Explanation" including sub-sections "Analogs" and "Information and Analogs" to "Analog Operations", "Analog Signals" and the sub-section "Noise". Is there any point to this redundancy? GBMorris 13:11, 16 August 2006 (UTC)

You are right. MAh, that's incredible, this article is really in a mess. Also please give a look at "Power electronics", where the section References is empty. Dr. Who 23:20, 16 August 2006 (UTC)

Major Remake

I felt that this page needed a major workover, since its in some instances lacking information, misliding or incorrect. This is my first post of an article, and any coments or corrections will be apreciated. Also, I do not have a lot of time to make this article into what is should be, but I think the end result is better than the orgiginal. Please let me know what do you think.

I agree that the page needed a rewrite, thanks for making a start NightHawk. I have had a go at rewording some of it to make it easier to understand, but there is still a fair bit to do. For example improving the links and references, perhaps adding citations for some of the predictions made at the end, etc. etc. Alf Boggis 12:23, 18 September 2006 (UTC)
