Talk:Waveform

Completeness

To match the article to the title, this article is nowhere near general enough. All waveforms should be considered. They are not all signals varying with time. It needs to be totally rewritten - I am sure good sources can be found on the Internet - I suggest textbooks, and they don't need to be modern, as the topic is not modern. When I say all waveforms I do not mean all possible shapes in every medium should be listed. However all waveforms have certain general characteristics such as wavelength, period, amplitude, etc. none of which I see here. If you mean oscilloscope signals or electrical signals then the title and intro should make that clear, but this is all waveforms. I would expect to hear about geometry, repeating patterns and all those good generalities to be found in basic math and physics books or else this article should disappear and suddenly be found under "Oscilloscope signals", "Radio signals" or some such thing.Dave (talk) 00:06, 13 February 2008 (UTC)

PS. Ah well, I just discovered wave. But this article is not exactly wave, it is waveform, something that looks periodic either a representation or a natural shape. There would be some overlap no doubt. I could suggest we merge this into that but that is already long enough! I don't know what you are going to do. I would suggest either generalize and refer them back to wave or make it yet more specific by moving it to "electrical waveforms" or "oscilloscope waveforms." I can't work on it right now. If after a while I see it has been neglected I will throw on a template suggesting it be moved to oscilloscope waveforms.Dave (talk) 00:19, 13 February 2008 (UTC)

I agree completely. The referenced "definition" is very lacking. Waveforms are generally the result of any sensor as a function of any independent variable. It is common to have waveforms in either the time domain or the frequency domain, but needn't be restricted to that. 73.68.108.105 (talk) 11:01, 22 March 2022 (UTC)

Integral of square wave?

Excuse me, but the integrand of a square wave is NOT a triangle wave. Rather it is the absolute value of triangle wave.Akilaa (talk) 15:51, 20 October 2009 (UTC)

Either way, it's triangular shaped; is there a relevant definition for the distinction you're making? Dicklyon (talk) 21:49, 20 October 2009 (UTC)

http://www.techterms.com/definition/waveform

A waveform is an image that represents an audio signal or recording. It shows the changes in amplitude over a certain amount of time. The amplitude of the signal is measured on the y-axis (vertically), while time is measured on the x-axis (horizontally).

Most audio recording programs show waveforms to give the user a visual idea of what has been recorded. If the waveform is very low and not pronounced, the recording was probably very soft. It the waveform almost fills the entire image, the recording may have been too "hot" or recorded with the levels set too high. Changes in a waveform are also good indicators as too when certain parts of a recording take place. For example, the waveform may be small when there is just a vocalist singing, but may become much larger when the drums and guitar come in. This visual representation enables audio producers to locate certain parts of a song without even listening to the recording. —Preceding unsigned comment added by 69.107.99.218 (talk) 05:10, 26 May 2010 (UTC)

I don't think there was any doubt about the definition of waveform. Maybe of triangular waveform. Though the original point was silly, since integration has a free offset in general. Dicklyon (talk) 05:19, 26 May 2010 (UTC)

A problem with the LaTeX code in the page.

There is a problem with the LaTeX code in the second section. This is the text displayed:

Failed to parse (syntax error): {\displaystyle (t,\lambda) = \operatorname{saw}(t,\lambda) − \operatorname{saw}(t − \frac{\lambda}{2 },\lambda)} — Preceding unsigned comment added by 77.138.244.73 (talk) 09:19, 12 November 2016 (UTC)

No links to the word in regard to physics

I was looking for information on the applications in physics but I could find no reference or relevant links on this page, nor on the disambiguation page, meaning that when one googles the word, no Wikipedia pages about physics appear and there's no obvious way to find one from that search. I've never edited on Wikipedia before and am not confident that I could fix it correctly. Dogface07 (talk) 07:57, 16 May 2023 (UTC)
