Except that considerations of reflections and their effects
on impedence only become relevant when the length of the
connection is some fairly signifigant percentage of the
wavelength of the signal.
In signal transmission, rather than power transmission, it
is the effects of impedence on accurate delivery of the
signal that matters.
