Re: No, No, No...

Yes, I looked it up and yes I am definitely confusing differential with balanced. There is a difference after all.

Still, if you replace differential with balanced in there, it will work fine for most of what I wrote, I think. I'm not sure of anything anymore. But now I say a floating differential is a disaster waiting to happen when you try to couple that to a grounded secondary. You need a drain to ground for differential signals everywhere somehow, even if the resistance is large. The only thing that should float completely are DVM's that measure the circuit.

I bet the phone company uses center-tapped points to Earth ground along the way. That keeps the static down for the reasons I stated. And I still contend you can do well with twisted pairs in unbalanced circuits, most of the time. I wrote the condition where it doesn't work so well, when both ends of the "hot" wire is at a high impedance from ground.

Am I right about anything here, or am I just full of shit all the way? I need to know in order to decide whether to quit my day job.
