Reflections are functions of TIME, not frequency.

Oliver Heaviside had the right idea long before the invention of the

For "reflections" also read "Echos".

Hi Reggie,

You are in fact wrong in all accounts. Reflections are functions of
distance - as are echoes. This is a phase issue. Time and frequency
are always inseparable as Kelvin would instruct you in first
principles before another hunk of chalk was winged off your noggin.

You may choose to render phase into time, but shift the frequency and
the phase shifts, not the distance. Mismatched Zo connectors do not
shrink or enlarge with frequency - the effects may, but physical
components rarely follow such perturbations.... until an arc-over
that is the classic failure mechanism for such mismatches (obviously,
and deliberately ignored in this thread).
