I dedicate this book to my daughters Julie and Meredith, I wish I could go with you; to my Mother Ruth for making me finish my homework; to my Father Grady who didn't know what he started when he built that workbench in the basement; to my brother Ray for improving us all; to my brother Ken who succeeded where I failed; to my sister Nancy for running interference for us; and to the skilled folk on the USENET newsgroup comp.dsp, they ask the good questions and provide the best answers. Finally to Sigi Pardula (Batgirl), without your keeping the place running this book wouldn't exist.
