Much of the new material in this edition results
from what I've learned from those clever folk on the USENET
newsgroup comp.dsp. (I could list a dozen names, but in doing so
I'd make 12 friends and 500 enemies.) So I say thanks to my DSP

For their patient efforts in the unpleasant task
of reviewing early versions of the manuscript, I was lucky to have
help from the talented Eric Jacobsen, Dr. Peter Kootsookos, Matthew
Donadio, Dr. Ian Buckner, Dr. Mike Rosing, Jerry Olup, Clay S.
Turner, Ray Andraka, Jim Thomas, Robert Bristow-Johnson, Julius
Kusuma, and Dr. Ing. Rune Allnor. Thanks guys, I owe you.
I also thank Patty Donovan, of Pine Tree
Composition, Inc., for converting the jumbled mess of papers
plopped on her desk into a readable book; Production Gurus Lisa
Iarkowski and Anne Garcia, of Prentice Hall, for skillfully riding
herd on the publication process; and my upbeat Acquisition Editor
Bernard Goodwin for his generous encouragement and
 "A publisher
lives by what he feels. Authors do too, but authors are blind moles
working their solitary way along their individual tunnels; the
publisher is like the Pied Piper of Hamelin, piping his way along a
path he wants them to follow" (Lovat Dickson).
If you're still with me this far into the
