DCT

Hi Oli, I posted that link to my write-up of using the DCT in FFTW to do derivative calculations. I think it is a unique bit of info that is not included in the DCT page, and would be of interest to people who are reading the DCT article (or probably the spectral methods article too). I understand that 'no blogs' is so people don't spam wikipediea, but read the article I linked to! It is a how-to of using FFTW to apply the DCT to a useful mathematical operation. How is that spam? If I had put the same article on a Google Knol page, would you have deleted the link?

Grammar

Would you care to cite a reference for that rule? Oli Filth^{(talk|contribs)} 19:17, 31 May 2009 (UTC)

My English teacher taught it to me and it is in the style guide of every technical manual type that I hav had to write.

A google on 'an versus a' turns up no shortage of references. The most comprehensive discussion is blocked by Wikipedia for some reason. Just to add confusion to the problem, there appear to be a number of apparently authoritative sites that are clearly not run by any recogniseable authority - mostly American judging by the examples. (Bit like Battery University which looks like an authoritative site but is run by a private individual). 86.145.21.227 (talk) 19:33, 31 May 2009 (UTC)

Are you saying that you were specifically taught that "a" precedes "H" (or "F", "L", "M", "N", "S" or "X") in the context of an initialism? I can't find anything on the web that would agree with that, even if I search for "an versus a", and the first paragraph of A and an disagrees. On that Google search, I've found at least two that explicitly disagree: [1] and [2].

If you do find anything that supports this notion then please post it here, but if so this would probably then need to go to a wider audience as it would affect countless Wikipedia articles (e.g. HVAC, HDMI, HSBC, H-bridge, XML, MRI, FFT, MP). Oli Filth^{(talk|contribs)} 19:44, 31 May 2009 (UTC)

I just changed the Cascaded integrator-comb filter page from "an" to "a" a minute ago, just to have you change it back a few minutes later. I think it is funny and cool that someone changed it so quickly. This is my first experience in editing wikipedia pages, and I am far from a grammar expert. At first I could not think of a reason someone would use "an" in that context. I don't know how much you actually know about the whole signal processing world, I am just learning about it myself, but everyone pronounces the acronym, FIR, like "fur". So when I read it, it seamed completely incorrect. I see the reasoning behind the change now, but do you know what the actual rule is? I presume that if I have a conversation with someone, and I choose to pronounce it "fur", I would use "a", but I could see that in writing you would want to use "an", although I personally disagree with it. Nathan (talk) 15:50, 6 July 2009 (UTC)

I check my watchlist every hour or so while I'm at work, I guess it was just coincidental timing!

As for pronunciation, I generally hear it at work pronounced as separate letters ("F I R"). I would be tempted to stick with that for now, unless there's some compelling evidence that "fur" is dominant in the field... Regards, Oli Filth^{(talk|contribs)} 19:43, 6 July 2009 (UTC)

Thank you for deleting some hindu crap

Its good that you deleted that carp calling the Holy Kaaba a hindu temple.

Maximum length sequence‎‎ article

Hi. Can you please explain what you meant when you reverted my edit to the Maximum length sequence‎‎ article? If I remember correctly, the spectrum of a MLS is that of a sampled sinc^2() function, which is far from flat. Further more, it becomes even less flat for short sequences. The current statement appears to be misleading or just incorrect. -Roger (talk) 23:22, 8 June 2009 (UTC)

The DTFT (or DFT) of an MLS is flat (apart from the DC spike). You are correct that once converted back to the continuous domain, it has a non-flat spectrum, this didn't cross my mind when I read the article section. Perhaps we should clarify this distinction.

The Fourier Analysis-why the external link was put?

The Fourier Analysis The purpose of this module(http://www.nitte.ac.in/downloads/CTFS.pdf

) is to show step by step, using a very simple example(the Almost Square Wave), how the Fourier Series coefficients are determined. Only the minimum amount of the required theory is explained. So the reader, without getting lost in all the theoretical details, can develop a feel and liking for the subject.

The pre-requisite is the CONVOLUTION & LTI Systems module() which is already an external link in Wikipedia. —Preceding unsigned comment added by Ashok567 (talk • contribs) 14:28, 9 June 2009 (UTC)

Power Management

Oli - your first revision on this made sense because i put a link to my own organisation as well as the independent energy star, but your second makes no sense because I did not add a link to my company and actually removed two other advertisements. Your revison put back the adverts and removed energy star information. http://en.wikipedia.org/wiki/Power_management Verismic (talk) 22:52, 11 June 2009 (UTC)

Sorry, my mistake! I assumed you'd merely re-done your original edit. I've reverted my change. Regards, Oli Filth^{(talk|contribs)} 22:54, 11 June 2009 (UTC)

Thanks - you will see i reverted the other article - your call if you want to revert again, just be consistent with everyone else and I'm happy :) Verismic (talk) 22:59, 11 June 2009 (UTC)

Why the external link on Unit Impulse Function

Unit Impulse Function

Why this external link? (http://www.nitte.ac.in/downloads/Unit%20Impulse%20Function.pdf) The explanation of how δ(t) = ∞ at t = 0 in the definition of the Unit Impulse function is widely accepted. However, the explanation of δ(t) = ∞ does not explain why. The explanation provided in the link explains the reason how we get this δ(t) = ∞ is clear, correct and practical. It also gives insight into the meaning, definition and application of the Unit Impulse function. Ashok567 —Preceding unsigned comment added by Ashok567 (talk • contribs) 10:18, 12 June 2009 (UTC)

Why did you undo my edits?

You undid my addition of a missing alternative saying merely "External link only". What? Why? MBParker (talk) 02:12, 17 June 2009 (UTC)

Yeah, that was completely a good faith edit. And it was very useful. Alluullauua46 (talk) 02:15, 27 June 2009 (UTC)
