But now the man who admitted he doesn't know shit about digital design is suddenly an expert at it.

 TDR (time domain reflectometry) is mostly analog, not digital.  You
might argue that it can be used to impedance match transmission lines
and circuit traces on digital PCB's (printed circuit boards) or that
the required fast rise time pulse generator can be done digitally.
However, as long as the measurements are most commonly displayed on an
analog oscilloscope, methinks that TDR should be considered (mostly)
an analog technology.
 Also, there's nothing to "design" with TDR.  It's a measurement
technique performed using off the shelf test equipment.  Your claim
that to understand TDR somehow requires a digital designer suggests
that you haven't done any TDR measurements (with or without PWM) and
know little about what is involved.  This might help:

"Time Domain Reflectometry (TDR) has traditionally been used for
locating faults in cables."
 I've mentioned this previously, but it's worth repeating.  The way I
recognize expertise in any technical discipline is if the person
claiming expertise knows the vocabulary, buzzwords, acronyms, inside
jokes, and literature used by knowledgeable practitioners.  You have
repeatedly incorrectly spelled and misused technical terms that anyone
experienced in the field would be expected to know.
