Kent & C,
It's very interesting to see what has happened in the field I was
sideways involved in (in the mid-eighties) when we used Kalman Filtering
to describe EEG-signals in the time domain (of course we used FFT to
decribe it in the frequency domain) and we used pseudo-random generators
as noise source to reconstruct the EEG. We then encountered many
problems due to the pseudo-nature of the noise for which we developed
various countermeasure algorithms. Apparently this development goes on
until the current time.
If I remember correctly C., the Knuth you mentioned had already written
several articles on the subject in my time (we're getting old!!). But
I'm not a mathematician so most of it went over my head even then.
But it is a nice discussion althoguh grossly OT.
