Does making distortion measurement of cable make sense?

That's going to be great fun, especially on digital transmission cables :)
There was was a painful experience in professional audio industries where implementation of digital interconnections began well before consumer audio. There were considerable issues with early transmission of digital streams until such time as properly designed and terminated cables for digital interconnection were specified and available.

Cables made from unsuitable dielectric materials and/or with inappropriate construction, geometry or poor termination blurred the edge transitions of transmitted digital bits, often resulting in errors exceeding the error correction capacity of the receiver and muting the audio, or invoking error concealment techniques to recover audio. I remember a lot of expended sweat and tears in the performing arts part of professional audio.
 
On this very forum, people experimented with coat hanger wire, bananas, mud, etc... for transmitting audio signals from point A to point B. No audible difference was recorded. They must all be stone deaf, right?

Even more interesting are the tests where people hear a difference between one cable and itself. A switch is flipped, they hear a subtle change in the sound, As they keep listening, each time the switch is flipped they refine the perceived differences, and soon the difference is "not subtle". But then it turns out the switch wasn't connected...
 
Testing 50m!!! of Rg59!!! as speaker cable. Talk about over reaching to try to prove there point.

Add me to the group that thinks your the fool.
Do you have bad internet? If I give you other material, also in ENGLISH, where distortion is measured with short audio cables, you will say that this is fine print ... or are you just a chef by training? However, this is perhaps not much better for you than being afraid to look like a fool ...
 
Unfortunately, I don't know who SinGun is at all, but it seems that he was not afraid to look like a fool, like all real engineers ...
And also learn how to use books and articles, links to sources that authors point to in books and articles, and the Internet in general ...

Skin-effect does modulate a wire resistance.
This seems obvious to me.
The current density is not uniform at high frequencies. It is higher near the surface, lower inside. This results in an increase of the wire resistance.
But it works only for AC, so it changes impedance but not DC resistance. And as it was sayd yet - it isn't a non-linear effect. Thats a reason to forget about it if we are talking about distortions (that means non-linear effects).
 
Thanks, restarting the fun.
No problem, real engineers do know what is going on in here.
It would be funny if Nikola Tesla at one time would have consulted with the likes of you ... I wonder who he was considered at that time by the majority of the townsfolk? Surely something like a snake oil seller ... cooks only think about the oil, edible or not ...

Why do you ignore the question concerning your previous nick?
The answer is obvious: You are SinGun, trying to hide your identity.
Hey, you are soooo clever:p
Obviously, you have phobias and an inferiority complex in relation to your mind ... cook yourself something in snake oil, you have enough of it and it should heal ...
