This second edition text focuses on the fundamentals of digital signal processing with an emphasis on practical applications. In order to motivate students, many of the examples illustrate the processing of speech and music. This theme is also a focus of the course software that features facilities for recording and playing sound on a standard PC. The accompanying website contains a comprehensive MATLAB software package called the Fundamentals of Digital Signal Processing (FDSP) toolbox version 2.0. The FDSP toolbox includes chapter GUI modules, an extensive library of DSP functions, direct access to all of the computational examples, figures, and tables, solutions to selected problems, and online help documentation. Using the interactive GUI modules, students can explore, compare, and directly experience the effects of signal processing techniques without any need for programming.
- New design – now divided into three major parts I. Signal and System Analysis, II. Digital Filter Design, III. Advanced Signal Processing.
- Expanded introduction to signals and systems.
- New examples and case studies as well as numerous new end-of-chapter problems.
- New sections on system identification and equalization, the inclusion of a novel quadrature filter design technique, as well as a discussion of sigma-delta ADC.
- Important definitions, propositions, algorithms, tables, and case studies are now summarized at the end of chapter.
- Version 2.0 of the FDSP toolbox companion software with expanded functionality.
- Expanded treatment of many topics such as: difference equations and block diagrams; Noncausal signals and systems; the discrete-time Fourier transform (DTFT); zero-phase FIR filters; polyphase filter realizations; quadrature mirror filter banks.
- A graphical user interface (GUI) module is included at the end of each chapter that allows students to investigate meaningful numerical applications without any need for programming.
- An FDSP toolbox and computational problems are supplied for those users who are familiar with MATLAB or are prepared to learn it, and are interested in developing their own implementations.
- Important terms are set apart for convenient reference using definitions, and key results are stated as theorems in order to highlight their significance. Detailed algorithms are also included to summarize the steps used to implement important design procedures.
- Each chapter starts with a concise summary of student learning objectives, with each objective cross-referenced to a section or sections within the chapter.
- Motivation sections in each chapter introduce one or more examples of practical problems that can be solved using techniques covered in the chapter.
- A series of analysis tools and signal processing techniques applicable to the type of problems covered are introduced in each chapter. Within these sections the analysis methods and processing techniques go from simple to more complex.
- Each chapter concludes with a generous set of homework problems organized by section and problem type.
- Instructor's Solution Manual with complete solutions to all problems includes the functions, examples, figures, and problems from the text, all directly accessible from an easy to use GUI driver program available exclusively for instructors.
- Homework Builder Module helps instructors create and distribute homework assignments and solutions using problems selected from the end-of-chapter exercise set.
- Presents enough material, and sufficient flexibility in pedagogy, to provide for courses of different lengths.
- Experience with MATLAB programming is useful, but is not essential.
