Klaus,
   thanks for the Matlab files, I saw a lot of German text
in them.... I must enlist the aid of my wife to understand
what you wrote...

There is still a question I have. Probably the answer is
in what you sent me, if so, please bear with me.
You said that the lengths of the sincos tables must be coprime,
fine. The product of their lengths, together with the
sampling frequency, is what determines the minimum
resolution, fine. But, given that the above constraints
are respected, is it immaterial what lengths I choose,
or are there some other things you didn't say us yet ? :-)
