That was over 40 years ago, but I seem to remember that any discontinuity that

And of course, the same thing can happen in a simple system consisting
of
a TV source, a transmission line, and a mismatched load. TV ghosting
can
prove that the reflected traveling waves make multiple round trips to
the load
and back to the source, yet many continue to deny that proof. The best
(copout) argument that I have heard against it is that, "That is not
steady-state",
and therefore doesn't count. :-)
