and the same thing can the DFT do to a sampled version of the signal,
since the side bands will all be there.
I think the reall con against the spetral measurement is
its slowness. I have to average somehow and then I loose track of the
short time changes. Heisenberg biting again.

But what about Parsevals theorem? Can't that help?
