Hi there Sukhbinder Cmos or TTL? //Staigen

Hey Serge, do you know something about APF's block list, a file, i belive, that block IP numbers or adresses? Probably used at internet servers. Anyone else know about this list? Its purposes? //Staigen

Hi Zeppelin Many of us can't reach E-Lab at the moment! Not me, until now, not Ante, not Audioguru, and how many more that can't reach E-Lab at the moment, i dont know! This mean that the accuracy is 0.5%, plus/minus 1 number(count) //Staigen

Hi Serge I also want to say welcome to the forum! Nice to have you here ;D The font mess come from this board! Hopefully you will enjoy, and we hope you come with lots of reply's, questions and discussions! ;D //Staigen

Hi circuity Try to get a copy of the book "TTL COOKBOOK" by Don Lancaster, and read it, specially the chapter about intefaceing to real world. :) I belive amason.com have it, or at least a used one. You can also try to borrow it from your local library. If you found it as an E-book, please let us share it! //Staigen

Hi, sorry to interrupt One big error here, the yellow wire in a standard computer molex connector is 12V, and the red one is 5V! Maybee also the 5V regulator is connected wrong then! Check! //Staigen

Hi Isn't diff op-amp short for differential operational amplifier? Isn't op-amp also short for differential operational amplifier? Then your question dont make sense to me! ??? Correct me if i'm wrong! //Staigen

Hi Inuyasha No problem downloading or extracting that file, its a PDF file with total service instructions, if you want to, i can upload it here, as a zip file //Staigen

Hi fredigsm, velcome to this forum ;D Its right here on this site, in the projects area, here is a link: http://www.electronics-lab.com/projects/pc/index.html Have fun! ;D //Staigen

Hi John Have you looked in the EPE jan 2003 mag? I also have read about it in an article from 1930! //Staigen

Hey John, this wont give much out, there's an error in the drawing! The supply shoud be connected to the connection between the 1K resistor and the pot instead! Sorry //Staigen

Than you have to do your math then! Are you from Sweden? //Staigen

Yepp, i know that, and you know that, but the guy that wrote the book dont seems to know! Also, we dont know the answer or the facit yet, will you supply us with that, Sundin? //Staigen

So you like to do others homework, Audioguru? Well, i belive some of your answers will turn out to be wrong, too, in this teoretical questions! ;D ;D ;D Hehe //Staigen

Hi there sundin13, velcome to the forum! :) Sundin? Sounds like a Swedish name. Are you from Sweden? Some of the questions cant be answered, because there is a lack of some parameters! Vbe, for instance. But asume it is a perfect transistor(such transistor dont exist!) with a Vbe of zero votage and DCbeta=162. Question a: Since Vin=0V then Ib=0mA(uA,A), hence also Ic=0mA(uA,A), then the voltage across Rc=0V Question b: This one is harder, but it is only math! First you have to calculate the current throu Rc at saturation, then divide that with the beta value. If you calculate the Ic in other values than uA, then you have to convert the answer to uA. Question c: Here you can do the math in two ways. First way, divide the Vin voltage with the Ib current in uA, the answer is in Megohm, than convert to Kohm. Second way, convert the Ib current to mA, then divide the Vin voltage with that value, the answer is in mA. But watch out, there's a trap buildt in in this anwers! The trap only affects the c question. ??? ;D I belive you see the trap at once, once you have read throu the text once more. //Staigen

Thanks to you too keldean, i did not have some of the other! Then i miss most of the 2004 EPE Mags, have only jan and feb! //Staigen

Watch out EPE 2005-05 seems to be a stripped off version with no possibillities to manouvre in! Here is the full version //Staigen [attachment deleted by admin]

Maybee December would be nice too? //Staigen [attachment deleted by admin]

And November! //Staigen [attachment deleted by admin]

September? Here it is, hopefully! ??? ;D //Staigen [attachment deleted by admin]

Hi Logan I found the appnote on my computer in the end, it was not in the book! ;D I found two versions of it! Here they are: //Staigen AN-88.pdf AN-0088.pdf

Ok, but how goes "moore's law" ?

Hi There is an aplication note fron RCA about this, i will check later for the name of it! //Staigen

Hi Logan Your adviser is totally wrong, it can be used as an amplifier, and a good amp too! You almost had it working when your adviser took it apart from you, he should be ashamed! //Staigen

Hi rybitski Start by learning electronics, there are many good books right here on this site! In the "Articles" area, and also here in the postings, many of then uploaded by Ante. Good luck! //Staigen
