About Telecommunications
Product Description // 2003A-1, 0-13-020031-X, Warren Hioki, Telecommunications, 4/e// This introduction to the technical aspects of state-of-the-art telecommunications and data communications explores fundamental principles in a simplified, yet comprehensive and practical manner. Using exceptionally easy-to-read explanations and an abundance of drawings, tables, and charts, it explains both concepts and their applications. Text covers a broad range of telecommunication technologies, systems and standards including: noise, amplitude and frequency modulation, encoding technologies, the UART, modems, protocols, error detection, fiber optics and wireless communication. For individuals working in the telecommunications industry who are concerned with keeping abreast of the subject matter. From the Inside Flap PREFACE Telecommunications, Fourth Edition, has been upgraded to include more example problems, figures, tables, and a margin glossary, and covers the latest standards and emerging technologies developed in recent years. This book is intended to provide the reader with the technical aspects and background material on telecommunications, which is still one of the fastest-growing industries in the world. A broad range of topics is covered without the intricate details of mathematical derivations and proofs. Instead, fundamental principles are emphasized in a simplified yet comprehensive and practical manner. To achieve this, numerous sketches with detailed explanations are included throughout, all aimed at providing the reader with the practical knowledge needed by today's telecommunications engineer and technician. INTENDED AUDIENCE This book is intended primarily for use as a college text in data communications or telecommunications. A fundamental background in mathematics, electronics, and digital circuits is a helpful requirement to using the text. This text is of great value to undergraduates and graduates seeking to extend or renew their discipline. Furthermore, the myriad tables, figures, example problems, and telecommunication standards make it an excellent reference for faculty, students, and practitioners. Instructors will find the material clear, concise, and written with sufficient depth. Experiments can be easily implemented to reinforce example problems presented in the text. This book also serves as an excellent reference guide for those in the industry who want to keep abreast with the subject matter. For those interested in achieving some degree of computer literacy, a wealth of technical terms and acronyms are defined and discussed throughout. They are also included in an extensive glossary at the end of the book. ORGANIZATION OF THE TEXT The chapters in this text are arranged in an order that has been successfully presented in a series of telecommunications and data communications courses over the years. It is by no means the suggested order in which the material should be taught; some chapters may be covered independently of each other. For example, some instructors may choose to cover Chapter 13, Modems, prior to Chapter 12, The Telephone Network. The same may be true of Chapter 18, Fiber Optics, which, like many chapters, is a subject in itself. Chapters are organized as follows: Chapter 1, Introduction: An overview of telecommunications is presented in this chapter. Distinctions between analog and digital signals as well as data communications versus telecommunications are made. The 1996 Telecommunications Reform Act is also covered. Chapter 2, Noise: Noise is an inherent problem in any communication system. This chapter introduces the various types of noise, their characteristics, and their effects on the telecommunication system. Signal-to-noise ratio, noise figure, noise factor, relative versus absolute power gain, and decibel are also introduced. Several example problems are given. Chapter 3, Amplitude Modulation: The theory of AM is presented in this chapter. The frequency components
