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

[Review]

This volume provides an informed view of how information technology is shaping the contemporary humanities. It specifically reflects five ideals:
*humanities scholars with all levels of access are doing important work with technology;
*humanities scholars’ projects with technology reflect significant diversity, both across and within disciplinary bounds;
*using information technology in the humanities is a continuous conversation;
*information technology offers new options for humanities education; and
*just as collaboration changes the nature of any project, so does information technology change the nature of collaboration–its speed, character, methods, and possible implementations.


[Review]

Presents modern CMOS logic circuits, fabrication, and layout in a cohesive manner that links the material together with the system-level considerations.
* Chapter on Verilog HDL allows for rapid start-up.
* Illustrates the top-down design procedure used in modern VLSI chip design with an emphasis on variations in the HDL, logic, circuits and layout

This book covers all the basics of inspection and testing and clearly explains all the legal requirements. It not only tells you what tests are needed but also describes all of them step-by-step with the help of colour photos. Sample forms show how to verify recorded test results and how to certify and fill in the required documentation. The book is also packed with handy advice on how to avoid and solve common problems encountered on the job.
With its focus on the practical side of the actual inspection and testing rather than just the requirements of the regulations, this book is ideal for students, experienced electricians and those working in allied industries, such as plumbers and heating specialists, kitchen and bathroom fitters, alarm installers and others, whether they are working on domestic or industrial installations.

All the theory required for passing the City & Guilds Level 3 Certificate in Inspection, Testing and Certification of Electrical Installations (2391-01) is covered. The book also includes sample questions and scenarios as encountered in the exams. Questions encourage readers to research answers in the On-Site Guide, as required in the exams for Part P Competent Person courses from EAL, NICEIC, NAPIT, BPEC and others. Model answers are provided for all questions. The book will also help prepare students on City & Guilds 2330 Level 3 courses, NVQs and apprenticeship programmes for their practical inspection and testing exams.

Chris Kitcher is an Electrical Installation lecturer at Central Sussex College and has 45 years of experience in the electrical industry.

This book enables design engineers to be more effective in designing discrete and integrated circuits by helping them understand the role of analog devices in their circuit design. Analog elements are at the heart of many important functions in both discrete and integrated circuits, but from a design perspective the analog components are often the most difficult to understand. Examples include operational amplifiers, D/A and A/D converters and active filters. Effective circuit design requires a strong understanding of the operation of these analog devices and how they affect circuit design
