Digital Signal Processing Concepts

Abstract

The application of digital signal processing techniques to communications equipment design requires the use of several key principles. These principles are not difficult to understand; however, they are sufficiently different from analog design techniques to make a brief discussion regarding them desirable. This chapter presents several of the major concepts of transform theory and the properties of transforms, particularly as they relate to signal processing applications. The book then builds on these concepts in later chapters. The review is not intended to be a rigorous treatment of the subject. Rather, it is intended to cover those concepts that are frequently encountered in communications, and to present enough background to make the results plausible to the student and to the engineer. The reader will then have sufficient background to follow the material presented in subsequent chapters. The discussion begins with a brief treatment of signal representations.
