Sure, but Q is energy lost vs energy stored in one cycle. In a time
varying system what's the period of one cycle? Q is a nice shorthand
to compare various resonant systems, but except for trivial systems
it doesn't work all that well. Probably a better way to look at it is
in terms of phase noise.

"I think that the whole concept of Q and bandwidth is somewhat troubling
when applied to time varying systems. Certainly, the analysis it such
systems is more complex than we can deal with in a few short paragraphs
Correct. However, the concepts of stored and dissipated energy and
their ratios are simple enough for all to understand.
