Presumably this is another test you are
  • quite willing to pontificate about
  • but less eager to actually carry out
  • and if actually carried out on your product, the results are never to be divulged
In my very limited experience, this is called 'liquid BS from marketing'. Do you equate that with 'engineering'?

In English 'esoteric' carries a hint of occultism too, although it can just mean understood by a few, as Frank said. What we need is a word for 'unknowingly misunderstood by many' - that would better fit the topic of transmission lines.

I have add an image to my previous post. Is-it a problem if the individual schields of the pairs are in contact with the global shield ?

Do you have a record of your boom beach? You were talking about it so many times, it persists in my I want to hear it. It can be very relaxing. I suppose, being a beach boom, you imagination, But of course I hear the one from my own memory. Either soft warm and loving black sea, or cold pacific ocean. Different sounds, different temperatires... Different CHANGES of everything...
They sound different, of course. You can afford several electret capsules.

..but can you record drops on your head, caused by an ocean wave?

It is what Wavebourn is all about... Waves on the ocean. drops on your forehead... Equally reproduced... Miracle, but it works if you know what to preserve, and how to preserve.

As an aside, for a coax, there is no contribution of inductance for the outer shield anyway. The inductance of the coax is a direct function of the spacing between inner conductor and outer shield. Two wires at 90 degrees cannot cancel magnetic fields, the fields will add as a vector. That is why I am confused.[/B]

And, for lowering capacitance, have you looked at the driven-shield technique??

Does Zobel in this case deal with preshoot, or the lesser problem, overshoot?
