Opis

Digital Transmission Systems, Third Edition, is a comprehensive overview of the theory and practices of digital transmission systems used in digital communication. This new edition has been completely updated to include the latest technologies and newest techniques in the transmission of digitized information as well as coverage of digital transmission design, implementation and testing.
Highlights of this edition: -New material on error correction codes, multiple access, digital modulation, digital subscriber lines, cable modems, mobile wireless, wide area networks, and optical networks;
-Up-to-date industry standards and practices - including voice/video coding, digital subscriber lines, SONET/SDH, DWDM, ATM, broadband wireless access, network synchronization, and network management - are described and interpreted;
-Expanded problem sets (totaling over 300) at the end of each chapter for review and practice;
-All chapters have been updated with particular emphasis given to fiber optics, wireless and networks. The book is heavily illustrated with tables, figures and an abundance of examples and references to actual systems. Examples are from common carriers, manufacturers and the author's commercial experience. Telecommunications terms are defined and explained when first introduced.
Practicing engineers in the field of communication systems, managers and technical personnel in the IT industry, and students of electrical and communications engineering will find this an authoritative state-of-the-art resource.
