2channel8 A lot of theorizing. Very little empirical reporting. as fate would have it I wrote the first tests for the FAA to determine whether satellite communications delay would interfere with pilot to controller radio voice communication. Everyone and his brother knows voice (audio) signals over copper wire travel around 80% the speed of light which as everyone knows is 186,000 miles per second. There are other delays - i.e., through voice switches and other devices but the primary delay is the total up and down delay for a synchronous satellite at orbit of around 24,000 miles. Since the satellite delay is known to be 240 ms that means the velocity of the audio signal (voice) through free space is 186,000 miles per second. The speed of light. Now what is the only thing that can travel at the speed of light in free space? Answer at 11. |

, Your post, Just look at his website, then you’ll understand, why he can’thas corrupted the Agon page 2 of this thread making the page difficult to read. Please delete the post and re post the post without the last website link, or find another to post in its' place. Thank you. |

AL, (almarg) I am guilty of saying "current flows" in an AC circuit when answering questions regarding power branch circuits on audio forums. After reading Herman’s responses in this thread, https://forum.audiogon.com/discussions/directional-cables , I learned AC current does not flow back and forth in an AC circuit. I spent many hours on the net trying to prove him wrong only to find Herman is correct. For the purpose of this thread, regarding an audio signal applied to a wire cable, AC current flow in the cable just doesn’t hold water. IF, what is actually happening with the audio signal is that energy travels from the source to the load, (in one direction >>>), in the form of an electromagnetic wave, in my opinion, it then makes it easier to understand how cables can/could be directional. (Sorry for the double space. It was the only way to make the post easier to read.) Jim |
