Steve,
In theory you are right. Wanna bet we don't measure anything like it?!!
So much of theory is based on a supply of matched impedance or relative
stiffness and stability. It is based pretty much on steady state (CW)
conditions. (not always) and relies often on neat sine wave input.
Violate one of these parameters and any good scientist will walk away and
you'll have to actually do the measurments, real-time!
