I am not going anywhere. You need to think about what happens when you have reflections that range from, say......-8 dB, down to say, -46 dB.

Your crap is more likely -8 dB. My crap is -40 dB or less. Who needs to worry about cable length more?

I'm consistent. You can't seem to get your head screwed on in the right direction.

Either learn what reflections are, or don't waste my time. I have tried to explain it, and you seem more intent in believing what some shill has to say.

Jocko

How much more clear do I need to make this???????

Shorter cables are worse for reflections, because they will arrive too close to the decision point.

How many more times are you going to make me post this?

How much more effort do I need to expend to get you to understand what reflections are? I know what they are. CG and GM know what they are. Only you and this Lavry guy don't seem to understand.

Until you understand, it won't matter how long you make your cable.

Jocko

If your cable is a half wavelength (24m) then that's bad. A reflection will bounce off the receiver, then the source, and hit the receiver again right when the next transition is hitting the receiver. We'll call this the "least optimal length".

If you shorten your cable to 12m (1/4 wave), then the 1st reflection will hit the receiver exactly between the initial transition and the next. Which is optimal for reducing the effect of the 1st transition. However, the 2nd reflection will hit the receiver at the beginning of the next transition. The 2nd reflection should be considerably less in magnitude than the 1st, and much better than the fundamental, but you can argue that this isn't optimal either.

Shorten your cable to 8m (1/6 wave), the 1st reflection will hit 1/3 through the receiver interval, the 2nd will hit 2/3 through, and the 3rd will hit with the next transition. We're getting better once again.

Hold on a second, if you are saying that reflections are insignificant then why are "longer cables better" for jitter.
