Help your students focus on the development, implementation, and application of modern DSP techniques with DIGITAL SIGNAL PROCESSING USING MATLAB®, 3E. Written using an engaging, informal style, this book inspires students to become actively involved in each topic discussed. Each chapter starts with a motivational section that includes practical examples students can solve using the techniques covered in the chapter. Every chapter concludes with a detailed case study example, a chapter summary with student learning outcomes, and a generous selection of homework problems cross-referenced to sections within the chapter. A comprehensive DSP Companion software accompanies this edition for you to use inside the classroom and your students to use outside of the classroom. The DSP Companion software operates with MATLAB® and provides a plethora of options for class demonstrations and interactive student explorations of analysis and design concepts.
- NEW TOPICS HIGHLIGHT RECENT DEVELOPMENTS. Students study delayed first-order hold reconstruction filters, DFT analysis and syntheses filter banks, explicit tradeoff between time and frequency precision in spectrograms, practical constraints on filters with prescribed magnitude and phase characteristics, perfect reconstruction filter banks with simple criteria for sub-band filter design, transmultiplexor design with frequency division multiplexing over non-ideal communication channels and approximation of continuous functions of several variables using adaptive radial basis function networks.
- EXPANDED TREATMENT OF THE LATEST TOPICS PREPARES STUDENTS FOR SUCCESS. Explicit treatment of the Noble identities simplifies the discussion of polyphase filter design. This edition offers an improved discussion of adaptive FIR filter design using pseudo-filters and a streamlined explanation of nonlinear discrete-time system identification. The authors have also expanded this edition's presentation of least-squares system identification of ARMA, AR, and MA models.
- NEW EXAMPLES, FIGURES, AND TABLES THROUGHOUT FURTHER CLARIFY KEY CONCEPTS. New tables show the relationships between precision and the oversampling rate in oversampled ADCs and DACs. New examples, such as one that details processing MP3 music files with encoders and decoders, engage students and make content memorable.
- UPDATED DSP COMPANION SOFTWARE OFFERS NEW FUNCTIONALITY FOR STUDENTS AND TIME-SAVING RESOURCES FOR INSTRUCTORS. DSP Companion Software provides separate Student and Faculty versions compatible with the latest versions of Windows® and MATLAB®. A new Definitions menu option lets students view all definitions, propositions, and algorithms that appear in this edition. The Instructor version now includes a new Presentations menu option that displays more than 90 PowerPoint® lectures -- one for each section of every chapter.
- BOOK'S READER-FRIENDLY, CONVERSATIONAL WRITING STYLE INVITES ENGAGEMENT FROM STUDENTS. The authors have purposely written this text using an engaging, informal style that motivates students to delve into each new topic with interest.
- BROAD RANGE OF TOPICS PREPARES STUDENTS FOR VARIETY OF ON-THE-JOB CHALLENGES. This edition is specifically designed to provide a breadth of meaningful material and flexibility of content to accommodate courses of different lengths. For your convenience, the book is divided into three major parts: Signal and System Analysis, Digital Filter Design, and Advanced Signal Processing.
- STRUCTURED CHAPTERS HIGHLIGHT KEY POINTS AND EMPHASIZE REAL WORLD APPLICATIONS. Each chapter starts with a Motivation section that highlights practical examples and challenges that professionals can solve using techniques covered in the chapter. Specially marked sections denote more advanced or specialized material that you have the flexibility to omit without loss of continuity. Each chapter concludes with a detailed case study example that uses the techniques introduced in the chapter. A generous selection of homework problems provide numerous options for practice.
- DSP SOFTWARE CHAPTER GUI MODULES ALLOW STUDENTS TO EXPLORE AND MASTER DESIGN TOPICS. The chapter GUI modules feature a common user interface that is simple to use and easy to learn. These modules allow students to analyze design topics without requiring additional programming experience.

"The author's approach seems to me to be good and logical. The balance between theory, applications and using computer tools (MATLAB®, etc.) for verification is a very good balance. The concepts are well presented and described. The examples are more than adequate. The illustrations are in general very good. The range of topics discussed is very good. Using MATLAB® is a plus."
"Organization of material is fine. The approach to the topics presented in the text is good and it is consistent with the educational and learning process. The authors are paying attention to the level of the student's understanding and the need to motivate and illustrate concepts with examples and problem descriptions and guidance to appropriate solutions. The authors use good graphics, good side notes, good demarcations to break pace and mark important concepts as side-bars that pull the student's attention."
"I like the inclusion of a chapter summary at the end of each chapter. I think these short summary sections play an important role in the learning process. Overall, this is a solid textbook! Of course, the use of MATHLAB examples has become the standard in DSP courses, and it is well-represented in this textbook."
