- It has traditionaly been used has a convolution (filtering) shortcut but I also
- use it to correlate waves (pattern recognition).
-
- I even once read an article on how to use it to find greatest common
- divisors and as a factoring method!
-
- BTW, there are a lots of available transform that each have their own
- advantages. The newest emerging tool seams to be the 'wavelets'. See
- comp.dsp for details.
