Possible Merge[edit]

I created this page as requested in the Electronics wikiproject. I think that active and passive differentiators should probably be merged here. --Dbackes 20:18, 9 August 2006 (UTC)[reply]

I would think that perhaps it would be good, but looking at the length of the passive page, it just would look too bulky and akward (especially with all the formulas). I suggest keeping them seperate until perhaps the active one is created, then we could guage the length better and propose the merge once again. Radagast83 05:12, 6 November 2006 (UTC)[reply]

19 december 2012 edit[edit]

This edit of 19 december 2012 is not in good order: several elements indicate vandalism (related to C). Others are suspicious. Can any patroller clean this up?!Super48paul (talk) 14:51, 19 December 2012 (UTC)[reply]

I've reverted two edits. Well spotted. --Nigelj (talk) 15:16, 19 December 2012 (UTC)[reply]

Hey I don't have an account, but I think I saw an error on the page. Under capacitive reactance it originally said that it was directly proportional to the input voltage, while all the sources I've checked, including the electrical reactance page, show it being inversely proportional. I changed it, but I thought I'd say something. — Preceding unsigned comment added by 71.197.96.182 (talk) 03:33, 30 August 2013 (UTC)[reply]

Suggest merge[edit]

Passive differentiator circuit contains all the maths nicely typeset and could usefully be added to this article. We should probably also explain where and why and who would indulge in these kinky perversions, otherwise the reader's reaction will be "So What?" --Wtshymanski (talk) 16:53, 19 December 2012 (UTC)[reply]

"The minus sign indicates the phase difference of 180 degrees between the output and the input. The inverting input adds 90 degrees to the phase, and differentiating adds another 90 degrees." This isn't right. The inverting input changes the phase by 180 degrees and the differentiation by 90 degrees. The output is 90 degrees out of phase with the input for a sinusoidal input. I deleted this bullet point. — Preceding unsigned comment added by 86.30.159.57 (talk) 22:19, 25 November 2013 (UTC)[reply]
