We already have pages on resistor and capacitor. I therefore suggest you consider merging this page into them. Also I think the term circuit design is far too general for a single article,--Light current 01:00, 9 October 2005 (UTC)

If you could have a look at resistor and capacitor pages and see whether your new stuff would fit in there (rather than on cct design) then we can see what needs to be done. Dont worry about the size of the articles just yet. Thanks ;-)--Light current 01:27, 9 October 2005 (UTC)

If you are studying electronics/electrical engineering why not checkout WikiProject Electronics to see if you could help us and maybe join the project if you like. :-)--Light current 04:32, 9 October 2005 (UTC)

Why do we have so few engineers as Wikipedians?
I am trying to understand why there are so few Wikipedians who are graduate engineers. Once I get a grasp on that, perhaps I may be able to formulate some ideas on how to attract more experienced engineers to become Wikipedians. It would be very helpful if you would respond to these a few questions:


 * Are you a university graduate engineer?
 * Please indicate in which of these engineering disciplines you obtained your degree:
 * Aeronautical or aerospace engineering
 * Bioengineer or biological engineering
 * Chemical engineering
 * Civil engineering
 * Electrical engineering
 * Environmental engineering
 * Mechanical engineering
 * Petroleum engineering
 * Other
 * In what year did you obtain your degree?
 * What attracted you to participate in Wikipedia?

Please respond on my User talk:mbeychok page. Or you may respond to me via Wikipedia's email which I have enabled on my User:mbeychok page.

If you would rather not respond at all, that's fine also. Regards, - mbeychok 04:28, 4 May 2006 (UTC)

Invitation and Recommendations for writing articles on Hindi Wikipedia
 Hindi wikipedia invites and welcomes Wikipedians to contribute for the cause of spreading knowledge and the Hindi language. This page contains guidelines for writing a wiki-article on any topic at the Hindi Wikipedia, with special recommendations for writing in Hindi (Note: The script/font-family for Hindi is Devanāgari; the script/font-system for English is Roman script, also, the Hindi spelling system is not completely standardized). This article is yet in English language (mostly), in order to encourage even non-native/foreign people who have learnt/are learning Hindi to contribute to the Hindi wikipedia, and native Hindi speakers who normally write in English. The examples given below are only for explanation.

Recommendations:
 * 1) Firstly for proper viewing, it is recommended to keep all links NOT-UNDERLINED. Otherwise the मात्रा below the Hindi alphabets might get partly hidden behind the underlines. For this, please go to My Preferences (मेरी पसंद) at the top of the page, then click Misc., and then choose "underline links -> Never". Save your settings. Also, do not click yes for "justify paragraphs", otherwise on some browsers, the devanagari script will appear highly distorted.
 * 2) All users are requested and encouraged to contribute articles here, especially, to create new articles on general topics. They are also encouraged to expand the existing articles, and improve upon them. A non-user can also do the same; it is recommended but not required to register yourself as a wikipedian user at the Hindi wikipedia. As far as possible, each article should be written with a Neutral Point of View (NPOV)—no nationalistic or partiality or hatred based articles are welcome. The articles should be based on facts—and appropriate references should be provided as and where needed. See the English wiki's help page for editing in general. Almost all the general wiki-features are available for editing on Hindi wiki too. Guidelines for the content matter is mostly the same as given in English wiki.
 * 3) Since the Hindi wiki is at its initial stages, users are welcome to take introduction and basic points from the English (or another) wikipedia's corresponding article and translate them for small articles. An in-page link to the English wiki's article will be deemed sufficient for references (a template might be created stating this). For longer articles, it is recommended to mention the references separately.
 * 4) Since most computer users in India and elsewhere have the standard Western-type keyboard, it is best recommended (but not necessarily required) to use the virtual (software) keyboard like the one of Hindimozhi or of ISIS (Tavultesoft Keyman)—which are freewares. These are advantageous because the contemporary Hindi-speakers in India often write messages/chat using Hindi words but written in Roman (English) script, and the layout of these keyboards is quite the same that such people use. For example, using the "normal" keyboard with this software, typing ga would give ग and ghaa would give घा.
 * 5) Create the article with its name written in Hindi (devanagari script). Always take care to include the nukta (dot below) for foreign / Urdu loanwords wherever it occurs in the standard spelling. For non-Indian names, use that spelling (for article name and other words) which is commonly encountered in Hindi newspapers, G.K.-books, Hindi-dubbed TV documentaries and Hollywood films and magazines. e.g., America-अमरीका (या अमेरिका), China-चीन, French-फ़्रांसिसी. For English acronyms/short-forms, use the initials in Roman script, and again create a full form in Hindi and redirect it to the short form. e.g. IPA (अन्तर्राष्ट्रीय ध्वनि वर्णाक्षर); UNO (संयुक्त राष्ट्र संघ). Doing the opposite is also fine. But creating the article with the Hindi short form, as सं०रा०सं०, is not recommended. Also, the article proper must be written with the proper nukta, as फ़ारसी, and then, a non-nukta (mis-)spelt version फारसी should preferably be created to redirect to the correct spelling.
 * 6) Hindi wikipedia strongly recommends the users to write articles in everyday common Hindi in the खड़ीबोली dialect (Hindustani or Hindi-Urdu, i.e., बोलचाल वाली हिन्दी, which may include many loanwords from Persian and Arabic). The use of शुद्ध संस्कृतनिष्ठ हिन्दी is in general neither required nor recommended. E.g., use: वजह instead of कारण, ख़ास instead of विशेष, वगैरह instead of इत्यादि, लेकिन instead of परन्तु etc. However, for technical and specialized vocabulary, the use of शुद्ध संस्कृतनिष्ठ हिन्दी  is recommended and usually mandatory. Thus: upper House of Parliament—संसद का उच्च सदन, but not Urdu—मजिलिस का ऐवान-ए-बाला ; Foreign Minister—विदेशमन्त्री, but not Urdu—वज़ीर-ए-ख़ारिजा ; knowledge/science—ज्ञान/विज्ञान, but not इल्म. Use spoken Hindi's ये and वो instead of यह and वह / वे. Do not use the title of respect जी after names, it is unencyclopedic. Thus: कृष्ण / श्री कृष्ण but not कृष्ण जी. Use the आप form and its corresponding 3rd person verbal conjugation for writing about respectable persons. Thus: श्री वाजपेयी मध्य प्रदेश में जन्मे थे. But not: वाजपेयी मध्य प्रदेश में जन्मा था. But do not use the pronoun "आप" itself in-text in biographies.
 * 7) English should be used sparingly, only when required; i.e., if the corresponding शुद्ध हिन्दी word is too "difficult and not generally encountered", or if it is a proper name of non-Indian person/place/terminology/title, or if the user is highly unsure of the proper translation. It is recommended (but not required) for English-to-Hindi translation while writing articles, the Shabdkosh online dictionary should be used. For each English word, that alternative should be used which is generally encountered in everyday spoken Hindi, and also fits well into the context. Use of intelligent guesses for newly encountered words is also allowed, and so are translations encountered in Hindi-dubbed TV documentaries, Hollywood films, Hindi-translated books, etc. e.g., दमपिशाच for en:Dementor (used in dubbed HP films).
 * 8) If used, it is recommended to use the English words within the articles using the English (Roman) alphabets rather than devanagari (or better, the devanagari transliteration should be used in the sentence, followed by the English word in Roman alphabet in parentheses). Such words should be italicized and not put in quotation marks. Preferably, there should be an in-page interwiki link (like :en:) on the word to the English wikipedia. If the word comes as an integral part of a sentence, so as not to break the continuity, the en: prefix should be hidden by writing the word again after the pipe sign (piped link). Thus, recommended:  Whence,
 * 9) *हैरी पॉटर ने Pensieve के अन्दर Little Hangleton गाँव में लॉर्ड वोल्डेमॉर्ट की माँ Merope Gaunt को देखा
 * 10) *Resplendent Quetzal पक्षी के ऊपर एक मेक्सिकन पादरी डा० Pablo de la Llave ने काफ़ी शोध किया था
 * 11) Always start the first 1 or 2 lines of the article giving its definition (from any standard dictionary/other wiki) or suitable introduction. Thus, recommended: ललिता सहस्रनामन हिन्दू धर्मसुधारक आदि शंकराचार्य द्वारा रचित देवी दुर्गा को समर्पित एक पूजा-मन्त्र है, जिसे कई हिन्दू रोज़ श्रद्धा से जपते हैं । But not: ललिता सहस्रनामन मन्त्र जपने के लिये लड्डू-पेड़ा, ताम्बुल, सिन्दूर, लाल चुनरी के साथ नित्य इस मन्त्र का पाठ करें, तो जल्द ही गड़ा हुआ ख़जाना मिलेगा । Recommended: वैमानिक अभियान्त्रिकी (en:Aeronautical engineering) विमानों (en:Aircrafts) की अभिकल्पना, निर्माण और प्रचालन करने का विज्ञान, कला और कार्य है । (translated from Eng. Webster's New World Dictionary). But not: आजकल वैमानिक अभियान्त्रिकी के लिये देशभर में कई कॉलेज खुल गये हैं, जिनमें अग्रणी स्थान यूटोपिया स्थित लालू-यादव टेक्लिनक कॉलेज का है ।
 * 12) For names of countries, cities, places, languages, people, books, films, technical vocabulary, mythology, etc, start the article like this:
 * 13) * 1.
 * 14) * 2.
 * 15) * 3. phonological transcription
 * 16) * 4.  For country names, only the standard short form of the name is needed in the first line. If there is a common name for a difficult word in Hindustani, also mention it. Whence: अपोलो (अंग्रेज़ी : en:Apollo; यूनानी : Aπollων अपोल्लोन) प्राचीन यूनानी धर्म (ग्रीक धर्म) और प्राचीन रोमन धर्म के सर्वोच्च देवता थे । If you don't give the interwiki English/another language link (which would be deemed to be the default reference), then you MUST provide an appropriate reference.
 * 17) Please leave no article without an appropriate category. See the list of created categories here; you can also make a new category (pref. in Hindi). Please leave no article without at least ONE off page (like en:) interwiki link. E.g., the user can check the article name (say Apollo) on the finally redirected English page and append to the Hindi article . These interlanguage links will help a bot to update all interwiki links for that article in all wikipedias. The category and the aforementioned link should be typed at the end of the article. If the article is very small, mention it as a stub/substub.
 * 18) Use of templates is welcome. See the list of templates here. If creating a template, name it pref. in Hindi.
 * 19) Use पूर्णविराम ( । ) instead of a period (.) for ending statements. The पूर्णविराम, semicolon, colon and dash (but not comma) must come after one space after the word to prevent ambiguity. Use the international form of the Hindu-Arabic numerals (1,2,3 instead of १,२,३), as used by the Constitution and the Government of India (even for Hindi). There is no need to use the हलन्त at the end of Sanskrit words wherever it occurs. Hence, prefer: संसद over संसद्; अथर्वन over अथर्वन्. Use the proper quotation marks “” from the Insert toolbox, not "". Write dates as 2 मई 2006 (ईसवी or ईसापूर्व). Write time as 3:45 pm. Separate common suffix-words like शास्त्र, विज्ञान, ज्ञान with a hyphen. Thus: रसायन-शास्त्र. For most others, leave both the words of the noun-cluster free. Combine them into one word only if it is very common to do so. Thus: सामवेद.
 * 20) The use of ज़ for the en:voiced alveolar fricative (/z/, as in zoo, rose) is fundamentally wrong. Its nearest counterpart is the en:voiceless alveolar fricative /s/ (as in sea), and not Hindi ज (en:voiced palatal plosive). Hence, it is suggested and recommended that for the sound /z/, whether it comes in English (etc.) spellings (z) for while pronunciation otherwise, should be transcribed as स़ (स with a dot below, available in the Insert toolbox). Hence: Reason रीस़न, not रीज़न ; Roses रोस़ेस़, not रोज़ेज़. But common Hindi words borrowed from Persian/Arabic (so-called Urdu words) are allowed to continue with ज़ spelling. Thus: ज़रा, नज़र, तर्ज़. The en:voiced postalveolar fricative (/ʒ/ as in treasure), inexistent in Hindi, can similarly be transcribed with श़. Thus: treasure ट्रॅश़र. The nukta (dot) available in the Insert toolbox can be combined with various consonants to suggest a more exact phonetic devanagari rendering of foreign sounds. E.g., since phonetically, English Think and this are not equal to थिंक and दिस, a better transcription could be थ़िंक and द़िस. Please take care of the dot below in so-called Urdu words, otherwise the Hindi spelling is deemed incorrect.
 * 21) For the following English vowels met, mate, mat, transcribe as मॅट (short vowel), मेट (not मेइट), मैट (not मॅट, as popular in Marathi). However in contemporary Hindi and here, it is acceptable to use ए instead of ऍ. Thus: अमेरिका is more popular than अमॅरिका. For cot, coat, caught, transcribe as कॉट, कोट, कॉट (not कौट). Transcribe English /t/ and /d/ as ट and ड.
 * 22) Use half-न before त, थ, द, ध, न, instead of anuswaar अं. Use half-म before प, फ, ब, भ, म. Use the anuswaar before all the rest of the consonants (not half-ङ, ञ, ण). If the मात्रा is not above the alphabet, use chandra-bindu, but only for nasalization. Thus: अन्दर, not अंदर ; अन्त, not अंत ; हिन्दी, not हिंदी ; सम्भव, not संभव ; पंचमी, not पञ्चमी ; अंडा, not अण्डा ; कंठ, not कण्ठ ; लैंड, not लैण्ड ; आँख, not आंख. However, both forms are acceptable in contemporary Hindi as well as here; the prec. are just recommendations.
 * 23) When proceded by another vowel, use the pure vowels instead of य (unless the य is clearly articulated while pronouncing). Thus : जाएँ, not जायें (not जावें) ; आएगा, not आयेगा . However, both forms are acceptable in contemporary Hindi as well as here.
 * 24) Please pay careful attention to the masculine/feminine gender (and singular/plural) in adjectives and verbs, else the sentence becomes ungrammatical.

For more information/suggestions/criticisms, please contact any one of the administrators of Hindi wiki here, preferably en:User:Magicalsaumy.

Wikiproject Electronics collaboration
Hi, I am writing to you because you have listed yourself as a member of the Electronics WikiProject. Sadly, this project is pretty dead, but I propose to resuscitate it with a collaboration. The idea is to have a concerted effort on improving one article per month, hopefully to GA or FA status and nominate the very best of them for the front page. I have prepared a page to control this process at WikiProject Electronics/Collaboration (actually, I mostly shamelessly stole it from WikiProject Mammals where a collaboration of this sort was succesfully run). There you can make nominations for articles for collaboration or comment on the nominations of others.

If you want to take part you might like to place this template  on your userpage which will give you a link to the current collaboration. If you are no longer interested in Wikiproject Electronics, please remove yourself from the members list, which is now at WikiProject Electronics/Members

WikiProject Space reorganization
Hello WikiProject Space member! A discussion has been started regarding the future of WikiProject Space here; any comments you might have would be welcome! There are mainly two competing ideas:


 * 1) Centralize all the Space-related WikiProjects, such as Astronomy and Spaceflight, and merge them into WikiProject Space, or
 * 2) Separate the Astronomy and Spaceflight "sides" of WikiProject, and remove WikiProject Space.

If you can think of other options, that's great too. Your contribution to the discussion would be much appreciated. Thanks! :)

Images at Chebyshev filter
I have reverted your replacement of the figures at Chebyshev filter as I am not convinced they are accurate, although I am willing to be convinced otherwise. They are quite different curves from the original pngs and a few spot checks seems to indicate the originals are correct. For instance the second zero of a fifth order type 2 Chebyshev with ripple of ε=0.01 (40 dB) I make occurs at 1.701 whereas your graph has it occuring at around 2.7.

 * What makes you think I am using software? I checked with a hand calculation.  Most of what you need is at Chebyshev polynomial.  Why are you so determined to replace these images?  They are perfectly ok, drawn at a high enough resolution to look good on the page.  I think this campaign to replace absolutely all png graphs is rather misguided: many of them are prefectly servicable and often take up less disk space than the replacement svg.  There are a whole heap of really crappy, low-res, pixelated bitmap images on Wikipedia.  Why don't you go find some of those to work on instead?  Spinning  Spark  00:33, 19 June 2011 (UTC)

Error in one of the PNG files
I noticed an error on a diagram for poly-phase rectification.

The peaks on the 3-phase full-wave rectification do not match up with the peaks of the individual phases. The error occurred after 17-Jun-2011; the first instance is "17:04, 22 September 2011" http://upload.wikimedia.org/wikipedia/commons/archive/2/2e/20110922172043%213_phase_rectification_2.svg

On a side note, one time I was looking at the schematics for the linear power supply for a PDP-10 model KL. It had a "missing phase" detector, which was triggered by excessive fluctuations on the 360 Hz ripple current when one of the three input phases dropped out. I mention this as something interesting to be added to a full-wave rectification article. Joeinwap (talk) 00:24, 27 March 2012 (UTC)

Light wave harmonics
Hi Krishnavedala,

I noticed you replaced one of my images with a svg version. It looks really good, except I might point out that light waves are always perfect sine-waves. Therefore, the image is no longer drawn to scale, as the caption in the article reads. The amplitude is always the same, so adding amplitude to the image is rather unnecessary, as it distorts the actual wave shape. The difference in energy is determined solely by frequency. This is the same reason microwaves can be blocked by a screen and produce specular reflection off of sand, whereas light waves will pass right through a screen and diffuse in sand. Other than that, the image looks really good to me. (My computer won't do svg files.) Zaereth (talk) 21:36, 6 April 2015 (UTC).
 * Thank you Zaereth. I also included the source code to generate the image. As you can see, it generates perfect sine waveforms. In your previous image, they looked like semi-circles connected together. The only limitation in the image is the sampling rate at higher frequencies. All the sine-waves have the frequencies proportionally scaled with each other and hence are to-the-scale in time, frequency and phase. The amplitudes are also maintained identical in all the waveforms and are to-the-scale. If you find any descrepancies, do let know and I will try to rectify them. --Rubber Duck (☮ • ✍) 02:16, 7 April 2015 (UTC)


 * Well, I may be wrong, but that's how I've always understood the physical shape of the actual wave to be when translated into two dimensions, from working with lasers and optical flats. A true sine-wave follows the exact rise and fall depicted in trigonometry, so that the height of the wave matches the length, as opposed to a sinusoidal, or "sine-like," wave. (Height in this case being a measure of physical shape, not amplitude.) Of course, I may be misinterpreting things, so feel free to correct me if I'm wrong. I actually made the picture after a little experimenting to see how the wave forms matched up to what I was seeing on my flats when tested in both monochromatic and white light, and the match was perfect in all cases, providing I maintained a true sine-wave.

changings in svg
Hi Krishnavedala, in August 2014 you have uploaded the file: Fixed capacitors overview.svg that you have transformed from my jpg file E-cap-family-14-02-02.jpg from jpg into svg format. I like this svg format, however I am a little bit older and I do not can create or change pictures in svg format.

Two things have changed in the meantime in this picture and I would ask you to change your file Fixed capacitors overview.svg.

1) please change under “Electrolytic capacitors → Aluminum electrolytic capacitors → the text in the middle block from “solid MnO2” into “Hybrid polymer”. The solid Al-MnO2 e-caps are nearly obsolete now and hybrid polymer Al-capacitors are running fast..

2) please change under “Niobium electrolytic capacitors” → “solid polymer” either the line of the block into a dotted line which I would prefer or delete the block “solid polymer”. The production of polymer niobium capacitors is ceased.

Thanks for helping and best regards --Elcap (talk) 13:56, 25 August 2015 (UTC)
 * Done! Thank you for bringing these changes to my notice :) --Rubber Duck (☮ • ✍) 15:50, 31 August 2015 (UTC)
