The opening says Electronic noise is an unwanted signal characteristic, but that is not true. There are applications for using (and generating) noise. Otherwise you wouldn't have things like [1] [2] [3]. They're mostly for crypto, but I think I've seen uses in ham-radio (can't dig up the info ATM). Yngvarr (c) 12:06, 14 April 2008 (UTC)
- Noise does refer to unwanted signal characteristics, technically. This is not true in common usage. The examples provided refer to specific spectra whereas "noise" is not a specific spectrum. Some types of noise do have colors used in their name to identify different spectra, however, none of these is also represented by a particular pattern in the time domain. In the frequency domain there is only one graphical representation.

While noise is generally unwanted, it can serve a useful purpose in some applications, such as random number generation or dither.This is paritally supported by Noise (electronics) § Dither. ~ Kvng ( talk) 19:37, 13 August 2021 (UTC)

I think it will be appropriate that a description of the effects of noise be also included in the article. This could be in the form of noise that produces a noise emf or a noise current. Many students of electrical and electronic circuits would be interested to know what the resulting effect is; how exactly is the real or wanted signal affected by the emf or current fluctuations.

I dont know if this belongs here, but couldnt find anywhere more relevant. I present an anecdote only because of a lack of known terms for it: I will hear constant buzzing of electronics. I can her it change frequency during power surges. It was incredibly obvious during the days when CRT displays were everywhere. Going to places empty of such electronics, like a desert, would very obviously not have this noise.
If this is the place for this, then I think a section on audible electronic noise would be very useful here. If this isn't the right place for this, my apologies, though I would ask to be corrected and given the actual term for this. 74.132.249.206 ( talk) 02:34, 15 November 2011 (UTC)

G'day, I hope that you are going to go back to the Noise (electronics) article and copyedit it, because what you reinstated is dreadful. Cheers YSSYguy ( talk) 12:52, 3 June 2013 (UTC)

I suggest merging noise generator into noise (electronics). Currently there seems to be a lot of overlap between the two articles -- both articles have descriptions of thermal noise, shot noise, avalanche noise, etc. Imagine a single article covering all three of (1) physical sources of noise, (2) techniques to minimize unwanted noise, and (3) techniques to deliberately amplify and collect "noise" as a noise generator. I suspect such an article will much shorter than the total length of 3 separate articles to cover the same topics, and so it simplifies things to cover them all together in one article. -- DavidCary ( talk) 02:58, 22 August 2014 (UTC)
I think they work best as separate topics. Yes, the noise generator articles talks about how various electronic devices and noise mechanisms can be used, but it's still a pretty separate topic. Dicklyon ( talk) 04:33, 22 August 2014 (UTC)
