The solved exercises cover all of the techniques discussed in the text, and include step-by-step instruction on working through the algorithms.

    It can serve both as an excellent introduction for the graduate student with some background in probability theory or as a valuable reference for the practicing ommunication system engineer. For both communities, the treatment is clear and well presented." - Andrew Viterbi, The Viterbi Group Master every key digital communications technology, concept, and technique. Digital Communications, Second Edition is a thoroughly revised and updated edition of the field's classic, best-selling introduction. With remarkable clarity, Dr. Bernard Sklar introduces every digital communication technology at the heart of today's wireless and Internet revolutions, providing a unified structure and context for understanding them -- all without sacrificing mathematical precision. Sklar begins by introducing the fundamentals of signals, spectra, formatting, and baseband transmission. Next, he presents practical coverage of virtually every contemporary modulation, coding, and signal processing technique, with numeric examples and step-by-step implementation guidance. Coverage includes: Signals and processing steps: from information source through transmitter, channel, receiver, and information sinkKey tradeoffs: signal-to-noise ratios, probability of error, and bandwidth expenditureTrellis-coded modulation and Reed-Solomon codes: what's behind the mathSynchronization and spread spectrum solutionsFading channels: causes, effects, and techniques for withstanding fadingThe first complete how-to guide to turbo codes: squeezing maximum performance out of digital connectionsImplementing encryption with PGP, the de facto industry standard Whether you're building wireless systems, xDSL, fiber or coax-based services, satellite networks, or Internet infrastructure, Sklar presents the theory and the practical implementation details you need. With nearly 500 illustrations and 300 problems and exercises, there's never been a faster way to master advanced digital communications. CD-ROM INCLUDED The CD-ROM contains a complete educational version of Elanix' SystemView DSP design software, as well as detailed notes for getting started, a comprehensive DSP tutorial, and over 50 additional communications exercises.

    What happened to the Christian church over the 2000 years since the Day Of Pentecost? Why are there so many denominations? How did it happen? This book, written in easy to read literary style contains a detailed study of the Seven Church Ages.

    These machines are finding ever-increasing applications, typically in position control systems, robotics and mechatronics, electric vehicles, and high speed transportation. A particular feature of this book is that it does not stop at the basic principles of these complex machines but goes on to cover recent developments and current research, making it useful for senior graduate students and research scholars in the field of electrical machines and drives.

    Its coverage progresses from an introduction through the evolution of switching systems and electromechanical systems to stored-program-controlled digital systems and future broadband systems. Coverage includes: modern digital networks; modern digital switching systems; digital transmission, including synchronous digital hierarchy; broadband networks including ATM; and integrated services digital network (ISDN). The book is intended for use on graduate courses in telecommunications.

    

    

    Blends academic precision and practical experience in an authoritative introduction to basic principles of digital design and practical requirements. With over 30 years of experience in both industrial and university settings, the author covers the most widespread logic design practices while building a solid foundation of theoretical and engineering principles for students to use as they go forward in this fast moving field.

    Intended for professional development programs in introductory database management.

    Comprehensive coverage includes traditional analog systems, as well as modern digital techniques. Extensive discussion of today's modern wireless systems- including cellular, radio, paging systems, and wireless data networks- is also included. In addition, sections on data communication and the internet, high-definition television, and fiber optics have been updated in this edition to enable readers to keep pace with the latest technological advancements. A block-diagram approach is emphasized throughout the book, with circuits included when helpful to lead readers to an understanding of fundamental principles. Instructive, step-by-step examples using MultiSIM, in addition to those that use actual equipment and current manufacturer's specifications, are also included. Knowledge of basic algebra and trigonometry is assumed, yet no calculus is required.

    It is an easy to understand, pocket sized manual with a durable, water resistant cover. It contains illustrations such as solving rolling offsets, centers of 15o, 22-1/2o and 60o butt weld elbows cut from a 90o elbow. It also contains layouts for a true Y layout, common pipe angles and their solutions, special offsets and solutions, mitered pipe cuts, multi-piece mitered turns and much more.

    Although the sound is muffled, the raised voices, suspicious thuds, and tortured gurgles lead them to believe that what they�re hearing is a brutal murder, unintentionally left as a voice message. As they try to decide what to do next, they are forced to consider a terrifying thought: What will happen when the killer realizes his mistake?
