== your revert of my edit in article [[characteristic impedance]] ==
Regarding your revert https://en.wikipedia.org/w/index.php?title=Characteristic_impedance&oldid=prev&diff=1217577555 : I follow up on your revert comment "Already clarified in the same sentence. I'll be glad to help if you think I missed your intention.".
So the statement in the article as-is is the following:
> The '''characteristic impedance''' or '''surge impedance''' (usually written Z<sub>0</sub>) of a uniform [[transmission line]] is the ratio of the amplitudes of [[voltage]] and [[Electric current|current]] of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of [[Reflections of signals on conducting lines|reflections]] in the other direction.
So I assue "already clarified in the same sentence" refers to "a wave travelling in one direction in the absence of reflections in the other directions".
This statement does not make it clear to me what a "single wave" is. The term "single wave" is still vague.
Exemplary suggestive questions that come here up are:
* is a single wave a single period?
* is a single wave a single frequency?
* is it a "packet of energy" / impulse?
* What makes a signal/wave a "travelling wave"?
Thank you very much with providing more insights, e.g. by further extending the explanation, by linking to a definite article, or by creating such article for "single wave". [[User:Abdull|Abdull]] ([[User talk:Abdull|talk]]) 09:35, 9 April 2024 (UTC)
