I have to start with a big thanks to Peter Cook for getting me started on the right track in the first place. To Wieslaw Woszczyk for allowing me to teach courses at McGill back when I was still just a novice idiot - the best way to learn something is to have to teach it to someone else. To Alain Terriault, Gilbert Soulodre and Michel Lavoie for answering my dumb questions about electronics when I was just starting to get the hang of exactly what things like a capacitor or an op amp do in a circuit. To Brian Sarvis and Kypros Christodoulides who were patient enough to put up with my subsequent dumb questions regarding what things like diodes and transistors do in a circuit. To Jason Corey for putting up with me running down many a wrong track looking for answers to some of the questions found in here. To Mark Ballora for patiently answering questions about DSP and trying (unsuccessfully) to get me to understand Shakespeare. Finally to Philippe Depalle - once upon a time I was taking a course in DSP for dummies at McGill and, about two-thirds of the way through the semester, Philippe guest-taught for one class. In that class, I wound up taking more notes than I had for all classes in the previous part of the semester combined. Since then, Philippe came to be a full-time faculty at McGill and I was lucky enough to have him as a thesis advisor. Basically, when I have any questions about anything, Philippe is the person I ask. I also have to thank a number of people who have proofread some of the stuff you'll find here and have offered assistance and corrections - either with or without being asked. In alphabetical order, these folks are Bruce Bartlett, Peter Cook, Goran Finnberg, John La Grou, George Massenburg, Bert Noeth, Ray Rayburn, Eberhard Sengpiel and Greg Simmons. Also on the list of thanks are people who have given permission to use their materials. Thanks to Claudia Haase and Thomas Lischker at RTW Radio-Technische (http://www.rtw.dewww.rtw.de) for their kind permission to use graphics from their product line for the section on levels and meters. Also to George Massenburg (http://www.massenburg.comwww.massenburg.com) for permission to duplicate a chapter from the GML manual on equalizers that I wrote for him. There are also a large number of people who have emailed me, either to ask questions about things that I didn't explain well enough the first time, or to make suggestions regarding additions to the book. I'll list those people in a later update of the text - but thanks to you if you're in that group. Finally, thanks to Jonathan Sheaffer and The Jordan Valley Academic College (http://www.yarden.ac.ilwww.yarden.ac.il) for hosting the space to put this file back when it was a growing (and still free) online book. Now that I'm charging money for it, I can pay for my own bandwidth.
