"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. ....... Phil |

"Paul Hovnanian P.E." HiggsField wrote: "Phil Allison" ** For "uk.rec.audio" readers. Absolute overkill, and it appears that the construction style would lead to HUGE capacitance levels. Capacitance? Where? Not an issue between strands in the same conductor. They are at the same potential. The capacitance between the two conductors would be no worse than that of any stranded conductor twin lead (zip cord). ** Get real - the strands of the two conductors are * interwoven * so there is a large increase in cable capacitance over a comparable twin wire lead. About 20 to 30 times. But this extra C disappears if the cable is terminated in a zobel network with R = 8.2 ohms. This is (like?) Litz wire, used to keep skin effects and the resulting higher a.c. resistance down. ** That is a side benefit of using interwoven strands - the primary reason for which is to minimise cable inductance. .......

"HiggsField" No, it isn't. The weave has a few purposes. It is MAINLY so that one can pass the run under a rug, and it will lay fairly flat, compared to that same circular mil area in a solid or stranded "single conductor" pair, paralleled or twisted. ** The cable in my pic is 7mm round and will not compress as it has an inner plastic core. The inter weave is to reduce cable inductance to a minimum. Another function is to quell external influences from changing an instantaneous potential into a value it was not originally. ** Tin hat logic. Another function is high flexibility with low capacity for mechanical breakage. ** It is reasonably tough stuff. So the main reason, electrically speaking is to get as much copper area into as flat a lay as possible. ** It will not lay flat. ....... Phil |

Another function is to quell external influences from changing an instantaneous potential into a value it was not originally. ** Tin hat logic. I can show you a standard DVN reading a voltage and observe the jitter in our noisy lab that creates... then twist the meter leads, and see how the jitter all but disappears. Noise cancellation IS one of the functions of the "cable". ** More tin hat logic ......... What has no observable effect in the application has no function. Yawnnnnnnnnnnnnn........ So the main reason, electrically speaking is to get as much copper area into as flat a lay as possible. ** It will not lay flat. Without the core tube, versions of that wire do, and it does not significantly increase inductance, and it DOES lay flat in such a scenario. Same exact construction except for the inner tube. ** More ****wit, tin hat logic. Misses the point by miles. ....... Phil |

I would venture to say that they have products that they are not even at liberty to tell you or some other normal ****tard that they have. For you to think that everything they make is commercially available is pretty goddamned arrogant, you stupid ****tard. There are plenty of companies that incorporate COTS parts in their contracted designs, but not every solution they require can be handled through COTS supply lines, therefore major portions of any given design can still incorporate custom made, single vendor only parts. Are you even able to grasp that concept? Do you even know what the term "same page" means, Johnny? You are out of your league. Post a link to a Moto VME product. Or keep babbling.
