bye.

Dave, From an engineering point of view I'm 100% with you. Seems as if we do not share the same experience - which doesn't fit to engineer's knowledge. Do we agree that we don't agree on how to cope with that? Ulli That's why you can't use an oscilloscope to what the signal eg for...

I do not have a written spec. +/- 1-2 Ω would be fine, I think... Oyaide SLSB BNC Plugs made me smile... $100 is for the plugs already... Be assured that the price tag does not in each and every case correlate with the result achieved. A borrowed $15.000 cable didn't make it - was...

Thanks a lot, jason. similar to my math skills ,-) As far as I know, text is part of a Taschenbuch der Hochfrequenztechnik. Apl. Prof. Dr.-Ing. habil. Harald Dalichau was teaching at http://www.unibw.de/eit5/front-page - seems to be retired, though he still appears under...

Why should the question for a certain formula being justified ? #5 and the discussion following is regraded being off topic by me. It neither gives an answer nor does it give any contribution to the thread question. Instead of giving an answer there was a discussion of why I want to do...

#4 asked an off topic question: That was answered by me in #5 - sorry for trying to be polite, #1 has my original question. #3 some clarification EOT

As far as I remember, I simply asked for a certain formula - quite a matter of "Physics or Engineering", right? May be it was not a good idea to answer off topic questions... I just wanted to be polite. I offline here. Ulli

That is exactly the question I'ld like to get an answer for ,-) When CD was introduced, I didn't like what I heard as some other did. All CD fans told me: "That's digital.That's just 0 and 1. That must be right! You are wrong by not accepting the truth." Later it turned out that jitter is...

sure. that's why i deleted my posting - not fast enough... L measures in H ,-)

solved see Bild 4a and equation (7) in mgk1.pdf. cheers Ulli

Thanks. Yes. Sort of: an ATtiny13 on a LT Demo Circuit board gives pulses watched with a 400 MHz scope: 100% agreeded. That's why I asked in my previous post to come back to my question, which is pure physics, I'ld say. Thanks for your comments. Ulli

Hi Dave, I agree completely With one remark: personal experience might be a reason for further investitagtion. I'm working on that, too. It's not so easy to find affordable measurment tools with high enough resolution. In a german forum Gert reported some measurements on how jitter...

That is true for lossless lines at high frequencies, I guess. Think about skin effect, for example. Here graph from a german manufactuar: http://www.tmr-audio.de/homemain/wissenswertes-ueber-hifi/faq/leitungen/111-wellenwiderstand-bei-nf-leitungen And bits are bits. Sorry, that's a too simple...

Sure. Apart from the shielding, I guess, this is mainly for the simple reason that controlling the impedance for 75 Ω is a bit tricky with wires in parallel. Sure. At least in theory. In the real world, different digital cables do produce different sound quality - I guess mainly do to...

Sure, in almost 100% the case wires do have the same diameter. A while ago I made an SPDIF cable with two wires in parallel. Lucky me, the cable plays music better than all commercial cables I've tried so far. Don't ask me why (but, of course, I would like to know how SPDIF transmission...
