Full Description
For courses in Digital Signal Processing. Designed especially for those new to the subject who do not have a background in linear systems or electrical engineering, this text provides an earlier, intuitive presentation. It integrates computer use with DSP theory and practice in all chapters. *Each chapter opens with an introductory application in DSP from one of the following fields: satellite communications, music synthesis, sonar, telephone communications, speech synthesis, seismology, and biomedical engineering. *Unique processing diagrams for use in developing DSP techniques Defines the signals used in the problem; how the signals are obtained and the types of operations that are being performed. Helps students to develop a solution and encourages them to add symbols or notation to the diagrams to describe a solution plan. *Careful explanations and many worked-out examples throughout. *Accompanying engineering data sets on disk Includes: A number of MATLAB files containing functions developed and used in the text; and a number of actual data sets that are referenced in the chapters e.g., one data file contains several seconds of a speech signal, and another data file contains data collected from a seismometer.
Allows students to use the DSP techniques of real data. *Frequent use of graphs using MATLAB. Illustrates concepts and presents examples, and provides a powerful means for visualizing the effects of DSP techniques. *A five-step problem solving approach. Helps students develop an approach to apply to solving a variety of problems. *MATLAB commands for solving each problem. Uses simple examples, and introduces the key features of MATLAB in an appendix. Shows students the power of MATLAB in performing engineering operations. *Revisits the chapter opening application at the end of each chapter and provides chapter-ending Application Problems. Allows students to apply the techniques developed within the chapter. *Concludes each chapter with a variety of exercises. Ranging from simple straight-forward problems to more advanced, thought-provoking problems. Assists students to understand and retain new topic material. *Ends each section with a Self-Test of short problems, with answers. Helps students to determine if they are ready to go on to the next section.
*Key words highlighted in italics, listed at the end of each chapter, and defined in an Index/Glossary at the end of the text.
