Download and read online ebook Digital Signal Transmission write by Chris Bissell. This book was released on 1992-08-20. Digital Signal Transmission available in PDF, EPUB and Kindle. This textbook will provide both undergraduates and practising engineers with an up-to-date and thorough grounding in the concepts of modern digital transmission. The book is not encyclopaedic, rather it selects the key concepts and processes and explains them in a deliberate pedagogic style. These concepts and processes are then illustrated by a number of system descriptions. The book is divided into three parts. The longest, Part II, describes the basic processes of digital transmission, such as matched filter detection, pulse shaping, line coding, channel coding, error detection and correction, etc. Understanding the concepts behind these processes requires a grasp of basic mathematical models, and this is provided in Part I. Finally, to put the processes in context, Part III describes elements of the public switched telephone network. The text is written throughout in a modern, digital context, and is comprehensively illustrated with helpful figures. Although the mathematical models (time- and frequency-domain concepts) have wider relevance, they are developed specifically for modelling digital signals. The processes described are those found in current transmission systems, and the description of the PSTN includes an outline of newly formulated standards for the synchronous digital hierarchy (SDH), SONET and for broadband ISDN (ATM). The book will be of great value to 2nd and 3rd year undergraduates studying telecommunications, as well as to graduate trainees and practising engineers. It is appropriate for either private study or as a text associated with a taught telecommunications course. The many worked examples and exercises with solutions will be particularly helpful.

Download and read online ebook Digital Signal Transmission write by Bryan Hart. This book was released on 2012-12-06. Digital Signal Transmission available in PDF, EPUB and Kindle. The coming of digital electronics has given rise to many textbook- outstanding among which are the authoritative works of Douglas Lewin- dealing, in the main, with the combinational and sequential logic aspects of system design. By comparison, the coverage of digital hardware has been meagre: in particular, books on logic circuit interconnections have been scarce in number. When circuits operated at relatively low speeds this did not cause major problems to engineers and students, but the increasing use of fast, and very fast, logic circuits employed extensively in modern digital systems has brought the requirement for properly-designed transmission paths between printed circuit boards, on the boards, and even in the integrated circuit packages themselves. turn, has necessitated a physical understanding of line pulse This, in behaviour, and an ability to design practically appropriate interconnection systems, by a far wider audience of engineers, scientists and students than has been the case hitherto. For many years the study of transmission lines was, primarily, the province of the telecommunications engineer sending high-frequency radio signals to antennas for radiation into space, and the power engineer working at low frequencies (50/60 Hz) but with corresponding wavelengths comparable with the relatively large distances involved in the supply of power from generating stations to remote users. The textbook treatment of lines was well established, but based mainly on the assumption of sinusoidal signals. This 'frequency-domain' approach is not best suited to the understanding of the transmission of digital signals.

Download and read online ebook Digital Speech Transmission write by Peter Vary. This book was released on 2006-08-04. Digital Speech Transmission available in PDF, EPUB and Kindle. The enormous advances in digital signal processing (DSP) technology have contributed to the wide dissemination and success of speech communication devices – be it GSM and UMTS mobile telephones, digital hearing aids, or human-machine interfaces. Digital speech transmission techniques play an important role in these applications, all the more because high quality speech transmission remains essential in all current and next generation communication networks. Enhancement, coding and error concealment techniques improve the transmitted speech signal at all stages of the transmission chain, from the acoustic front-end to the sound reproduction at the receiver. Advanced speech processing algorithms help to mitigate a number of physical and technological limitations such as background noise, bandwidth restrictions, shortage of radio frequencies, and transmission errors. Digital Speech Transmission provides a single-source, comprehensive guide to the fundamental issues, algorithms, standards, and trends in speech signal processing and speech communication technology. The authors give a solid, accessible overview of fundamentals of speech signal processing speech coding, including new speech coders for GSM and UMTS error concealment by soft decoding artificial bandwidth extension of speech signals single and multi-channel noise reduction acoustic echo cancellation This text is an invaluable resource for engineers, researchers, academics, and graduate students in the areas of communications, electrical engineering, and information technology.

Transmission Lines in Digital and Analog Electronic Systems available in PDF, EPUB and Kindle. In the last 30 years there have been dramatic changes in electrical technology--yet the length of the undergraduate curriculum has remained four years. Until some ten years ago, the analysis of transmission lines was a standard topic in the EE and CpE undergraduate curricula. Today most of the undergraduate curricula contain a rather brief study of the analysis of transmission lines in a one-semester junior-level course on electromagnetics. In some schools, this study of transmission lines is relegated to a senior technical elective or has disappeared from the curriculum altogether. This raises a serious problem in the preparation of EE and CpE undergraduates to be competent in the modern industrial world. For the reasons mentioned above, today's undergraduates lack the basic skills to design high-speed digital and high-frequency analog systems. It does little good to write sophisticated software if the hardware is unable to process the instructions. This problem will increase as the speeds and frequencies of these systems continue to increase seemingly without bound. This book is meant to repair that basic deficiency.
