Bruce,
Why would it make any difference? It would seem that as long as the
cable and connectors are stable, any reflections should be constant,
and the signal amplitude and phase should remain constant. So the
zero crossings at the receiver end should not change.
Where did I go wrong?
Thanks,
Mike Monett
