They will, but in that case both sides of the cable are unterminated; both hot and ground. With quasi-balanced the circuit is complete because the two wires inside the shield are carrying hot and ground so the circuit is complete. That's a totally different thing than a dangling length of 2 conductor coax. George Link to comment
Speedskater Posted April 25, 2018 Share Posted April 25, 2018 2 hours ago, marce said: I disagree somewhat the, cable is not directional as such, the shield is connected at one end only, this will only work with a return wire so not much good for co-ax cables. A shield connected at one end only at RF frequencies is actually called an antenna (usually forms a dipole). By 'shield' I meant. In an unbalanced or balanced interconnect a 2 conductor plus shield. (so the shield is only a shield) Yes a shield needs to be attached to a chassis at the connector or it becomes an antenna. Link to comment
Ralf11 Posted April 25, 2018 Share Posted April 25, 2018 the dialectical dielectrics ! Gummy - I said nothing incorrect - feel free to quote it if you think so now, as to "orientation of crystal boundaries formed during the drawing / [annealing] process"... I checked with a materials scientist (who informed me we are not allowed to call them metallurgists anymore) about this some time ago - there is a small effect that has been measured but it is of no interest for electrical transmission purposes also, let's not confuse the speed of electricity thru any medium with the translational movement of electrons themselves Below is something that is taught in Sophomore physics classes - they are only 19...

You said "no". I used used to think electrons just sort of vibrated or hovered in place — in fact they do move (slowly). I’m not trained in these topics, I’m just a neurotypical guy posting on the Internet. A signal is a flow of electricity. There is a direction. Energy jumping across conductor crystal boundaries effects the electrical properties of the conductor. That’s not at all controversial. Link to comment

What you are posting doesn’t make sense yet time and time again you post claiming that what you believe is considered “basic” or “well accepted” . Not sure what the repeated claims of “neurotypical”ity are about? Quote A signal is a flow of electricity. There is a direction. Energy jumping across conductor crystal boundaries effects the electrical properties of the conductor. That’s not at all controversial. Here’s your problem : a signal is not just “a flow of electricity” https://en.m.wikipedia.org/wiki/Signal Albeit the transmission of a signal may involve electrical current, there is no defined/fixed relationship between the direction of signal transmission and the direction of current flow. What you are saying indeed is not controversial — it’s just plain wrong. Now diodes affect current flow on a directional basis. It is trivial to construct a circuit which consists of diodes in parallel/series with resistors/capacitors and inductors. It is straightforward to measure the effects on electrical signals.

As always, there's a continuum of behaviour; at some level everything, including cables, alters some aspects of its behaviour, in measurable ways - depending upon everything. The debate is rather whether this is detectable by human hearing - those who are sensitive to these artifacts will register them; those whose beliefs make them determined that such can't be possible will make sure they can't hear them ... c'est la vie ...

No, this is really basic. Really basic. Read Wikipedia or a textbook. Please. If you can’t understand why the direction of signal transmission is not the same as the direction of current flow, I’m afraid there’s no hope for you to understand electronics.

jabbr Posted April 26, 2018 Share Posted April 26, 2018 Beating this horse because as @Ralf11 suggests, I also suspect it illustrates a wider problem than @GUTB understanding of signal transmission, and apropos to this thread because pseudo scientific marketing is used to promote ridiculous audiophile products -- I mean if you want to spend $100,000 on cables because you like their appearance, then fine, but don't because you've been sucked in by marketing prose. A "signal" is information. A signal is directional, information "moves" from one place to another. There is a source of information and a destination and the signal carries the information. There is a field of "information theory" which deals with signals. Indeed the source of the signal expends energy in its transmission, and so in this sense there can be considered an "energy flow" or "entropy gradient" that goes from the source of the signal to the destination. This flow is not directly a flow of electricity, or electrons. An "electrical signal" uses time varying voltages and currents to carry information. There is a difference: an electrical signal uses current flow, they aren't the same. Indeed in a balanced signal their is no net current flow because current in one direction is matched by the opposite current. Nonetheless the source expends energy and the signal is indeed directional. Now of course there are crystalline, semiconductor, doping, junction and other physical properties that do indeed affect directional current flow in electrical circuits, and it is possible that a cable could incorporate such elements but these properties are eminently measurable -- the characteristic curve of any transistor, or diode etc. etc. and short of that some marketing speak which discusses cable directionality based on some special crystalline structure is designed to make to think the cable is "special". There are very good reasons to use balanced signal transmission and now we would need to carefully think about the implications of cable strand asymmetry on balanced cables ... hmmm haven't heard about that, why?

Nonetheless the source expends energy and the signal is indeed directional. It should be noted that it need not be the source that expends energy. Imagine a pair of wires with a voltage source at one end and a switch at the other. By opening and closing the switch, a sender of information can cause current to flow or not. A receiver at the voltage source can monitor the current flow and thus decode the information. Here the receiver is the one expending energy by sending current through the loop. Link to comment
