## A Simple Approach to Digital Signal ProcessingA readable, understandable introduction to DSP for professionals and students alike . . . This practical guide is a welcome alternative to more complicated introductions to DSP. It assumes no prior DSP experience and takes the reader step–by–step through the most basic signal processing concepts to more complex functions and devices, including sampling, filtering, frequency transforms, data compression, and even DSP design decisions. The guide provides clear, concise explanations and examples, while keeping mathematics to a minimum, to help develop a fundamental understanding of DSP. Other features include: ∗ An extensive resource bibliography of more advanced DSP books. ∗ An example of a typical DSP system development cycle, including tool descriptions. ∗ A complete glossary of DSP–related acronyms Whether you′re a working engineer looking into DSP for the first time or an undergraduate struggling to comprehend the subject, this engaging introduction provides easy access to the basic knowledge that will lead to more advanced material. Texas Instruments has been designing and manufacturing single–chip DSP devices since 1982 and now produces eight distinct generations as part of the industry–standard TMS320 family. Much of this book is based on the experience TI gained in developing DSPs and training first–time users. |
