Digital and Analog Communication Systems

PREFACE Continuing the tradition of the first to fifth editions of this book, this new edition provides the latest up-to-date treatment of digital communication systems. It includes a number of new study-aid examples and homework problems, many of which require solutions via a personal computer. It is written as a textbook for junior or senior engineering students and is also appropriate for an introductory graduate course or as a modern technical reference for practicing electrical engineers. To learn about communication systems, it is essential to first understandhow communication systems work.Based on the principles of communications (power, frequency spectra, and Fourier analysis) that are covered in the first five chapters of this book, this understanding is motivated by the use of extensive examples, study-aid problems, and the inclusion of adopted standards. Especially interesting is the material on wire and wireless communication systems. Also of importance is the effect of noise on these systems, since, without noise (described by probability and random processes), one could communicate to the limits of the universe with negligible transmitted power. In summary, this book covers the essentials needed for the understanding of wire and wireless communication systems and includes adopted standards. These essentials are How communication systems work: Chapters 1 through 5. The effect of noise: Chapters 6 and 7. Wire and Wireless Communication Systems: Chapter 8. This, book is ideal for either a one-semester or a two-semester course. For a one-semester course, the basics of how communication systems work may be taught by using the first five chapters (with selected readings from Chapter 8). For a two-semester course, the whole book is used. This book coverspractical aspectsof communication systems developed from a soundtheoretical basis.
