User talk:Stevegrossman

Hi, Stevegrossman, Welcome  to Wikipedia! I hope you like this place &mdash; I sure do &mdash; and want to stay. Before getting too in-depth, you may want to read about the Five pillars of Wikipedia and simplified ruleset. If you need help on how to title new articles check out the naming conventions, and for help on formatting the pages visit the manual of style. If you need help look at Help and the FAQ, plus if you can't find your answer there, check the Village Pump (for Wikipedia related questions) or the Reference Desk (for general questions)! There's still more help at the Tutorial and Policy Library. Plus, don't forget to visit the Community Portal. And if you have any more questions after that, feel free to post them on my user talk page or place  on your talk page and someone will be by to help you shortly. ---

Additional tips
Here's some extra tips to help you get around in the 'pedia!
 * If you want to play around with your new Wiki skills the Sandbox is for you.
 * You can sign your name using three tildes (~). If you use four, you can add a datestamp too. Five will get you the datestamp only.
 * You may want to add yourself to the new user log.
 * If you ever think a page or image should be deleted, please list it at the votes for deletion page. There is also a votes for undeletion page if you want to retrieve something that you think should not have been deleted.
 * If you're still entirely confused, or would like to get a better grasp of your wikipedia skills, and you have an IRC client (or don't mind getting one), check out the Bootcamp. It's not what it sounds like, but it is fun and can help you with your editing skills.
 * If you're bored and want to find something to do, try the Random page button in the sidebar, or check out the Open Task message in the Community Portal.

Happy Wiki-ing. &mdash; Kf4bdy talk contribs

Quoting and referencing
Steve, take some time to learn how to be style-compatible with wikipedia articles. In particular, put your long quotes in blockquotes or something; look at other articles to find things to copy, or see WP:MOS and such. And use a proper reference format. By the way, are you associated wiht Pentek? Can you find a link that will go right to the material instead of to a login page? Dicklyon 16:04, 20 December 2006 (UTC)

Steve, I have not been able to find the online book you tried to reference from a bunch of articles. The Pentek site search doesn't find it and it keeps wanting me to log in when I try to get at stuff. I've reverted all your edits. Next time you're on wikipedia, take a look, consider my suggestion, and think about ways to add some of your information, quotes, references, etc. in a more compatible way. Dicklyon 16:49, 21 December 2006 (UTC)

Dick, I am a consultant to Pentek. I'll see if I can obtain a link that goes directly to the book. I'll try to fix the quotes. Could you give me a few more days to try and repair it before you decide definitely to delete it. I assume you also deleted the other 7 entries I'll look for your comments on those - as well. I certainly want to master whatever it is I have to know to measure up. I wrote one entry, "RuBee", last summer which apprently is still there and was not challenged. So you can appreciate my surprise at seeing all these eight entries being of questionible value.--Stevegrossman 23:58, 25 December 2006 (UTC)


 * Steve, generally speaking, wikipedia editors like me are pretty picky about external links, since they are so often "spam", added by people trying to bring some attention to their personal or commerical sites. I did revert most of your contributions, since, as I said, the format/style was not appropriate, and the referenced book was inaccessible, and the links seemed like spam.  However, I'm sure we'll welcome your expertise in these technical areas.  If the best way to include content is via quotes, copy a style from some other article, find an appropriate section to put it into, and learn how to create appropriate references; I just learn by copying, but there are lots of help pages available, too.

Aliasing
Aliasing is not always "undesirable". E.g., FFT channelizers rely on it as an efficient alternative to heterodyning for converting the frequency content of each channel from bandpass to lowpass. --Bob K 18:55, 21 December 2006 (UTC)
 * Bob, I think that's what he was trying to get at in the somewhat malformed article Decimating Low-pass filter, the only contribution that I did not revert. I think it's a nonstandard name for the concept, and it probably should be merged into another article, but I wasn't sure which one.
 * Steve, that one is a good example of the fact that you need to work on your image editing, too. Dicklyon 19:33, 21 December 2006 (UTC)


 * Dick, that article uses a "20 MHz local oscillator". That's the unnecessary heterodyne I was talking about.  Consider instead, a bandpass filter with 6 kHz bandwidth, centered at 20 MHz, and a complex sample-rate of 20.48 × $$10^6$$ samples/sec.  Decimating the sample-rate by 1024 (or equivalently: computing only every $$1024^{th}$$ output sample) yields a rate of only 20 kHz, which creates aliases of the filter output at 20 MHz ± k×20 kHz, for k = 1, 2, 3, 4, ...    And the k=1000 alias falls at 0 Hz, as desired.  --Bob K 19:15, 22 December 2006 (UTC)


 * Ah, yes, I see. The title implied to me that it was just using filtering and decimating.  I should have read it.  I think I'll propose it for deletion, as I find no backup for this terminology in books. Dicklyon 22:34, 22 December 2006 (UTC)

Steve, based on your emails, knowing you're sincere, I removed the proposed deletion tag. And I made a blockquote to show you how. And moved the article to a title with proper case to Decimating low-pass filter. Please work on getting the reference accessible, fixing the figure margins, more refs, better explanation in place of extensive quote, etc. Check Bob K's comments, too. Shouldn't a decimating LPF avoid the need for an LO? Or is it something that follows the LO mixer? Could be either way? Dicklyon 02:57, 26 December 2006 (UTC)

My Talk page
From now on make sure you attack the right person on the right page. I am not Dicklyon and I would appreciate it if you would refrain from calling me such on my own talk page! -- Kf4bdy talk contribs 03:53, 26 December 2006 (UTC)


 * Well, it's not the worst thing he could have accidentally called you ;^} Dicklyon 04:12, 26 December 2006 (UTC)
