Hey Keith, have you been able to disprove my figures
in my other thread "Please verify (or disprove)"?
If not, why not? Seems it would be an ideal time
to nail me to the wall with some math that disagrees
with mine.

Your math is typically fine (although you messed
up big time with your use of "reference"), when you
allow yourself to use it. It is the interpretations,
conclusions, and allocations of importance that
are flawed.

But now that you have declared black boxes a
conspiracy to hide "the facts", I'm thinking maybe
you should go join the MI5 guy.

Anyway, along the way you learned (or maybe
already knew and just articulated) that the effect
on the 600 ohm line is the same regardless of
the content of the black box producing -j567,
and for the black boxes, the phase shift at the
terminals is undecidable. And since the problem
can be solved without this information, it is also
irrelevant.

A bit of progress.

...Keith

8 to go.

Aha, so you agree that there is a 36.6 degree phase
shift between Vfor1 and Vfor2? That is certainly
progress. Now if you can only convince the gurus.

I didn't say all black boxes are a conspiracy to
hide the facts. But consider that when the goal
is to measure the phase shift at an impedance
discontinuity and someone insists on putting the
impedance discontinuity inside a black box where
the phase shift cannot possibly be measured, then
that person desperately wants to keep the results
from that measurement from being known.

Anyway, along the way you learned (or maybe
already knew and just articulated) that the effect
on the 600 ohm line is the same regardless of
the content of the black box producing -j567,


There was never any argument there so that statement
is just a straw man - go ahead and knock it down and
get it over with. Nobody disagrees with you.

and for the black boxes, the phase shift at the
terminals is undecidable. And since the problem
can be solved without this information, it is also
irrelevant.


The phase shift at the impedance discontinuity *CANNOT*
be solved without information about the impedance discontinuity.
Exactly what is it that you are so afraid that someone is
going to discover? The technical facts? You already admitted
that my calculations were accurate and valid. What more could
you possibly want to hide?
