Innovations in Telecommunications, Part A contains the proceedings of the symposium on "Innovations in Telecommunications" of the International Symposium Series held in Kuwait in April 1981 and sponsored by the Kuwait Foundation for the Advancement of Science. The symposium provided a forum for reviewing advances in research, development, demonstration, design, manufacture, field testing, and application in the field of telecommunications. Both the state of the art and the cutting edge of technology in telecommunications are given emphasis. Comprised of 17 chapters, this book is arranged in five major sections: signal processing; devices and microfabrication techniques; terrestrial communications; satellite communication; and applications. The discussion begins with an assessment of trends in electronic information transfer, followed by a description of a bandwidth- and power-efficient modulation system that combines convolutional encoding and phase modulation. Subsequent chapters deal with voice processing techniques; image processing for communication; developments in switching; and devices such as those for transmission and delta modulation. The final section is devoted to terrestrial communications and covers microwave systems, mobile and lightwave communications, and coaxial cable systems for land and sea. This monograph will be of interest to those in the telecommunications industry.

Describes and evaluates recent developments in the integration of passive components in wireless RF front ends, using real-world examples.

Wearable Sensors: Fundamentals, Implementation and Applications has been written by a collection of experts in their field, who each provide you with an understanding of how to design and work with wearable sensors. Together these insights provide the first single source of information on wearable sensors that would be a fantastic addition to the library of any engineers working in this field. Wearable Sensors covers a wide variety of topics associated with development and applications of wearable sensors. It also provides an overview and a coherent summary of many aspects of wearable sensor technology. Both professionals in industries and academic researchers need this package of information in order to learn the overview and each specific technology at the same time. This book includes the most current knowledge on the advancement of light-weight hardware, energy harvesting, signal processing, and wireless communications and networks. Practical problems with smart fabrics, biomonitoring and health informatics are all addressed, plus end user centric design, ethical and safety issues. The new edition is completely reviewed by key figures in the field, who offer authoritative and comprehensive information on the various topics. A new feature for the second edition is the incorporation of key background information on topics to allow the less advanced user access to the field and to make the title more of an auto-didactic book for undergraduates. - Provides a full revision of the first edition, providing a comprehensive and up-to-date resource of all currently used wearable devices in an accessible and structured manner - Helps engineers manufacture wearable devices with information on current technologies, with a focus on end user needs and recycling requirements - This book provides a fully updated overview of the many aspects of wearable sensor technology in one single volume, enabling engineers and researchers to fully comprehend the field and to identify opportunities

The tools and techniques to fully leverage coplanar technology Coplanar Microwave Integrated Circuits sets forth the theoretical underpinnings of coplanar waveguides and thoroughly examines the various coplanar components such as discontinuities, lumped elements, resonators, couplers, and filters, which are essential for microwave integrated circuit design. Based on the results of his own research findings, the author effectively demonstrates the many advantages of coplanar waveguide technology for modern circuit design. Following a brief introductory chapter, the text thoroughly covers the material needed for successful design and realization of coplanar microwave circuits, including: * Fundamental transmission properties of coplanar waveguides using a full wave analysis * Detailed analysis of most discontinuities used in coplanar waveguide design * Lumped elements in coplanar technology that are needed in circuit design * Development of software for coplanar circuit design, including a CD-ROM containing a test version of the software for modeling coplanar circuit components and circuits * Application of derived results to build more complex components such as lumped element filters, waveguide filters, millimeter wave filters, end-coupled waveguide structures, waveguide couplers, and Wilkinson couplers for different frequency ranges in coplanar technology The final chapter focuses on special coplanar microwave integrated circuits that have been developed using the software presented in the text. The book concludes with a thought-provoking discussion of the advantages and disadvantages of the coplanar technique. Extensive use of figures and tables helps readers easily digest and visualize complex concepts. A bibliography is included at the end of each chapter for further study and research. Coplanar Microwave Integrated Circuits is recommended for graduate students and engineers in RF microwaves who want to reap all the advantages and possibilities of coplanar technology.
