(One of the co-authors, Thad Welch, was recently selected as the first Signal Processing Engineering Network Fellow to recognize his leadership and contributions.) I am delighted to be able to have an opportunity to tell the readers of this text that they are in for, in the authors’ own words, “a ride ” Delores M Etter Texas Instruments Distinguished Chair in Electrical Engineering Executive Director, Caruth Institute for Engineering Education Lyle School of Engineering Southern Methodist University Dallas, Texas (Dr Etter is a member of the National Academy of Engineering and is a Fellow of the IEEE and of the American Society of Engineering Education She served as the Assistant Secretary of the Navy for Research, Development and Acquisitions from 2005–2007, and as the Deputy Under Secretary of Defense for Science and Technology from 1998–2001 She is also the author of a number of engineering textbooks, including several on MATLAB.) vii About the Authors Thad B Welch, Ph.D., P.E., is a Professor and past Chair of the Department of Electrical and Computer Engineering at Boise State University He previously taught in the Department of Electrical and Computer Engineering at both the U.S Naval Academy (USNA) and the U.S Air Force Academy (USAFA) A retired Commander in the U.S Navy, he was the inaugural 2011 SPEN Fellow, won the 2001 ECE Outstanding Educator Award, the 2002 Raouf Award for Excellence in the Teaching of Engineering, the John A Curtis Lecture Award from the Computers in Education Division of ASEE in 1998, 2005, and 2010, the 2003 ECE Outstanding Researcher Award at USNA, and the 1997 Clements Outstanding Educator Award at USAFA Dr Welch is the former Chair and a founding member of the Technical Committee on Signal Processing Education for the Institute of Electrical and Electronic Engineers (IEEE) Signal Processing Society He is a senior member of the IEEE and a member of the American Society for Engineering Education (ASEE), Tau Beta Pi (the engineering honor society), and Eta Kappa Nu (the electrical engineering honor society) Cameron H G Wright, Ph.D., P.E., is an Associate Professor and Associate Department Head in the Department of Electrical and Computer Engineering at the University of Wyoming, and previously taught for nearly 10 years at the U.S Air Force Academy (USAFA) in the Department of Electrical and Computer Engineering where he was Professor and Deputy Department Head A retired Lieutenant Colonel in the U.S Air Force, he won the Brigadier General R E Thomas Award for Outstanding Contributions to Cadet Education in 1992 and 1993 In 2005 and 2008, he won the IEEE Student Choice Award for Outstanding Professor of the Year, the Mortar Board “Top Prof” Award at the University of Wyoming in 2005 and 2007, the Outstanding Teaching Award from the ASEE Rocky Mountain Section in 2007, the John A Curtis Lecture Award from the Computers in Education Division of ASEE in 1998, 2005, and 2010, and the Tau Beta Pi WY-A chapter Undergraduate Teaching Award in 2011 Dr Wright is a founding member of the Technical Committee on Signal Processing Education for the IEEE Signal Processing Society, a senior member of the IEEE, and a member of ASEE, the National Society of Professional Engineers, the Biomedical Engineering Society, SPIE–The International Society of Optical Engineering, Tau Beta Pi, and Eta Kappa Nu Michael G Morrow, M.Eng.E.E., P.E., is a Faculty Associate in the Department of Electrical and Computer Engineering at the University of Wisconsin–Madison A retired Lieutenant Commander in the U.S Navy, he previously taught in the Electrical and Computer Engineering Engineering Department at the U.S Naval Academy and in the Department of Electrical and Computer Engineering at Boise State University Mr Morrow won both the 2002 Department of Electrical and Computer Engineering Outstanding Educator Award and the 2003 Gerald Holdridge Teaching Excellence ix ...Second Edition Real-Time Digital Signal Processing from MATLAB? ? to C with the TMS32 0C6 x DSPs This page intentionally left blank Second Edition Real-Time Digital Signal Processing from MATLAB? ? to. .. photocopy or use material electronically from this work, please access www.copyright.com (http:// www.copyright.com/) or contact the Copyright Clearance Center, Inc (CCC), 222 Rosewood Drive, Danvers,... sent to wireless networks Our noise-canceling headphones use adaptive digital signal processing to cancel the noise in the environment around us Digital cameras use digital signal processing to compress
