h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Hello,

I'm a community artist and we've been asked to illustrate the 'aliasing' section of your entry A882182 - Recording Techniques - Digital versus Analogue.
As a musician I'm somewhat familiar with the recording techniques and the aspects thereof you described in the entry. I've made a graphic at the following address. http://www.gondastudios.com/analog.gif
Please respond with comments on how to improve it.

Another artist, DrMO will probably be along to get your comments on another illustration for your entry.

Yes, perfect. Is this before or after sampling? Perhaps both. This would definitely help with the quantising explanation as well. Thanx

Sorry, just reread and took full notice of graph legend. Yes this is of great help indeed. Perhaps could do an exploding diagram with respect to sampling soundwaves into a digital system,or using one of the gifs to illustrate this (which would be a bloody sight easier). Thanks again.

The word from the editors was to do an illustration for the "aliasing" section, showing how a too-low sample rate could give the same digital data for two different analog waves. I'm not sure what you mean by an exploding diagram (though it sounds fun).

Don't worry, brain intercepting too much info!
Diagrams are excellent, I presume that the applicable diagram will go underneath the proper paragraph, so tht labelling is not such a problem. For the bass frequency diagram could you change the colour to red, so there is more contrast with the background.
Oh, an exploding diagram is a pic that shows constituent parts of a 3D object, so that each is a seperate entity. Err, if you wer to do a microphone youd do a pop sheild, to the right a diaphragm etc, all in 3D type drawing.

Red on a computer screen is a little hard on the eyes, and i'd like to keep it for the sample points. How about if I change it to a lighter blue?

I understand now what you mean by an exploding diagram. What exactly would you like me to draw in such a way?

Ok I've adjusted the colors a bit. Have another look.

Right, scince there is obvously two pics here, you must make sure with the Italics that this would be ok, because I have no problem with you doing the other one,

here is the graphic so far,

please forgive me for the banners (damb tripod)

thanks

Yes, they are perfect

If you had to choose one, Jose...

he dosn't have to... like I said, you step on my toes and I will not be pleased, but I don't mind you doing another graphic, so don't ask!

grumble, these new members, up to no good, wasn't like that back in the day when it started.

-- DoctorMO --

But they're both so good. Erm probably the former group, as less explanation is needed to go with the diagram. So there.

Unfortunatly it dosn't work like that, When there was a call for this graphic to be made I was first to reply, and as such the former should not have bursted in thinking he could do a better job, when what he should have done, is help peer review.

You don't get to choose anyway, just advise. I can see no problem in having both, but the italics probly will.

This is crule and rude,

Doc,
I am of the opinion - and not alone in it - that technical illustrations need to clarify the concept being described, and as such need to be done by someone with some knowledge of the concept. I hardly consiser myself an expert, but I at least had an idea of how to visually represent the idea described in the article. I don't mean to be cruel or rude, but your early diagrams show that you did not. I would even go so far as to say that you were way off base until you saw my drawing, and would never have arrived at that result had I not "stepped on your toes". You then produced another of your own, closely resembling mine, while pretending to retain precedence. However, members of the Community Artist's group and the author of the article itself have expressed a preference for mine.
This is not about feelings, unwritten rules, or aesthetic sense (as with normal editor's picks); it's about producing the best drawing for the article.

And it's not about producing the best graphic for the artical, if people were alowed to ram other people because of there lack of understanding you might as well be a poilition. I am under the impresion that your illerstration was an example to me, rather than a graphic of your own. Im sure there are quite a few picture I would have liked to do, but people got there first. life isn't fair! and it's based on people not results.

I personally found Il viagiatore's easier to follow, but this is probably because I know about sampling. If doing the Doctors diagram then repeat the digital sampling thingumy ie:

Low frequency wave
Sample pattern
High frequency wave
Sample Pattern

To clearly illustrate the point. Although Il vigiatores diagram was more concise it could confuse the 'layman/woman/person', probably

Doc,
You're describing the rules for normal editor's picks. If I thought I could make a better "Pre-Celtic Ireland" graphic than you, I wouldn't have said anything, since you picked it first. There's no special knowledge required to make a graphic for that article. And we wouldn't have been allowed to discuss it on the author's home page. None of this is true, however, for a technical illustration. Do you see the difference? Results are more important in this case.

I'm not sure what you mean by "poilition".

I think your tring to dodge the fact that instead of helping a fellow artist, you rolled over me. and I don't find that very nice, regardless of how well you knew the subject or how technical it is or infact how stupid I was at the time, you should have hellped me understand what was required, and you didn't. this isn't a competion this is suposed to be a comunity. I'll be dambed if I'm going to let people walk over me, regardless.

Do you not see?

Athough duplication of the information may make it more presise, I was aiming more for the way the information is encoded in the waves of digital signal, I thought if I do each difrent type, with all of the the same information, then it would make it clear that the information comes in these forms, instead of just comparing digital to each form of analog, you get the compare them all. , I'll change it if you like, and anything else, I'm so sorry for this little upset.

I think we've both made our points as well as we can. It's up to others to decide now.
