"flip top nut case "


** Characteristic impedance IS ALWAYS independent of cable length.

Cos it IS a " characteristic " of the cable and depends only on how
it
is made and the frequency.

The "characteristic impedance" is the impedance above the transition
region.


** Figure 7 SHOWS it is a valid parameter at all frequencies.

You're trying to make a faux case from the axis label on ONE graph
that even the title says is "Impedance vs. Frequency" and every other
graph that one is a composite of are labeled "Impedance vs.
Frequency.."


** The graph in Figure 7 is labelled " Characteristic Impedance (Ohms) "
and "Frequency (Hertz )".

The graphs in figures 4, 5 & 6 have " Zo " followed by formulae linked to
the curves and lines.

Zo = characteristic impedance.

So all these graphs are of CHARACTERISTIC IMPEDANCE.

You pathetic, blind as bat fool.



Quoting your source: "The characteristic impedance which is normally
listed in a cable catalog is this constant high frequency impedance."


** Which contradicts YOU - 100%.

Nope.

** Fraid it does - flip head.



The 'hundreds of ohms' comes
from the cable manufacturer's graph depicting what they claim is the
'characteristic impedance' of 'other' speaker cables.

** A perfectly correct set of graphs.

Characteristic impedance (or Zo) rises at lower frequencies for all
normal
cable types - the transition frequency is often in the middle of the
audio band.

I never said the graphs were 'wrong'.


** Yes you did, you flip head liar - you said it was "cow patty",

No,

** You did.


Only the ( electrically) short ones do not support standing waves.

Which is necessary for the impedance to matter.


** COMPLETELY WRONG !!!!!!!!!!!!!!!!!!!!

Completely right.

If the cable is 'short' relative to the wavelength (frequency) then
there is not 'enough' of it for the 'wave' to 'stand in', so to speak,
and the 'reflected' wave is essentially the same phase as the source,
so there can be no 'wave cancellation' or significant 'loading' of the
signal .


** Signal source loading is NOT due only to standing waves.

Transmission line behaviour does NOT depend on them.

THAT is your false assumption.



It matters in OTHER WAYS !!!!!!!!!!!

Care to explain what these "other ways" are?


** Cable capacitance and cable linear inductance.

Both can be made to vanish by Zo loading a cable.

This is what the topic is all about in relation to audio lines - cos there
is no issue with standing waves.



Remember, you just said "all cables" so the
question still remains for you to answer why the power cord works
instead of reflecting the power back from impedance mismatch.


** That is your own utterly mad, totally wrong idea.

Then explain why it works.

** No such thing needs explaining.



That is all well and good except they are presuming ....

** No they are not !!!!!!!!!!!!!!!

Yes, they are.


** Yaaawnnnnnnnnnnnnnn .....

Too dumb for words.



That is a QUOTE from the link you snipped out because your own
authoritative source says you're wrong.


** That is not any source I quoted.

Cos that fool makes the same dumb errors that many others have.



Just proves you can't read. The quoted words were cut and pasted from
the article beginning with the first sentence of the second paragraph
under figure 11 about midway in the paper: "You can see that, at low
frequencies, there is no "characteristic" impedance. It is always
changing. "


** That is just plain idiotic.

Just because a parameter varies with frequency don't mean it ceases to exist
!!!!

WOT A FOOL !!



The "desperate CHARLATAN !!!!" is you removing the reference from
your own authoritative source showing you're wrong.


** Not any source I linked at all.

Just some dumb fool with the same wrong ideas that radio hams sprout all
the time.
