ABSTRACT
Digital signal processing (DSP) has become an established area of electrical and computer engineering. Because all types of signals, when they are processed, are most often processed in digital form, scientists and engineers in all disciplines have come to at least a nodding acquaintance with the subject in order to understand what their instruments and displays are trying to tell them. Compared with other areas of electrical engineering that share their analytic tools with DSP, such as fields and waves, communication theory, circuits, and control theory, DSP has a relatively short history, a relatively rapid growth, and astonishing diversification into nearly every branch of technology. There are many special topics within DSP, such as image processing, digital communications, so that no one is an expert in all areas. Most of the DSP examples in the text use the MATLAB language. The chapter also presents an overview of the key concepts discussed in this book.
