The IEE in association with the IEEE and IERE organised an international specialist seminar on Advanced Signal Processing in Radar, Sonar and Communications, in September 1984. The Seminar was held at the University of Warwick and this book contains a collection of the papers presented. Some of the material is of a tutorial nature while some of it represents the latest state-of-the-art. Inevitably, because signal processing is limited by the components available, the subject matter ranges from the individual components and their impact on signal processing, through to the design and assessment of complete systems. The individual contributions come from industry, educational establishments and government research laboratories in the UK and the USA. The order of presentation in the book mainly follows the order in which the papers were presented at the seminar.
The fourth volume in the set, Analog Circuit Design: Designing Waveform-Processing Circuits, builds on the previous 3 volumes and presents a variety of analog non-amplifier circuits, including voltage references, current sources, filters, hysteresis switches and oscilloscope trigger and sweep circuitry, function generation, absolute-value circuits, and peak detectors. Digitizing (ADCs and DACs) and sampling (including some switched-capacitor) circuits are explained, with theory required for design. Sampling theory is developed from both a frequency and time-domain viewpoint, with emphasis upon application to design.

Signalling is the life-blood of telecommunications and common-channel signalling is the key to providing flexible and cost-effective services to customers. This book commences with the basics of signalling and then unveils the complexities of common-channel signalling systems. The book is written to appeal to a wide range of readership. The novice can build up a comprehensive understanding of signalling by systematically making progress through the book. Experts in telecommunications who wish to understand the specialist subject can select appropriate text, guided by the chapter summaries. Experts in signalling will find the book useful in extending their knowledge of a very broad subject. The glossary cuts through the maze of jargon.
The book describes basic principles, channel-associated signalling systems and the CCITT Signalling System No. 6. However, the focus of the book is upon common-channel signalling and CCITT Signalling System No. 7 and the Digital Subscriber Signalling System No. 1 are described in detail. The latest techniques are explained including, for example, the form of signalling required for gaining access to remote databases. The interworking of common-channel signalling systems is also described.
Engineering companies and other organizations face many serious challenges in the 21st Century. One that is now becoming widely recognized is the loss of corporate knowledge through staff turnover, whether it is natural or forced through downsizing or delayering. A company's store of knowledge and expertise is an asset built up through the learning and experience of its employees.
In this book the authors show that such loss of experience and knowledge can substantially erode corporate culture and impact upon a company's ability to develop and reinvent itself in response to its market. The concentration is on process, culture, structure and leadership, to assist engineering organizations in managing their valuable knowledge resources and the people who possess them. It provides effective methodologies to devise solutions to the real challenges faced by engineering managers today.
Illustrated with scenarios and practical examples, which will be familiar to engineers worldwide, this book represents great value to all those in engineering management practice. In addition, as management increasingly appears within the syllabus of engineering courses, it will interest engineering students preparing for careers in industry, as well as their educators.
The processing and analysis of signals and data is today a fast-growing and crucial activity in a diverse range of fields, not only in communications and image technology itself but in almost every other research area in science. The purpose of this book is to explain some of the theoretical concepts that underly the methods now in common use. The author starts from the assumption that some knowledge of the basic principles should be in the toolkit of every engineer or scientist working with signals or data.
Thus the book introduces the basic theory of discrete-time systems, processes and signals including discrete transforms. It explains classical digital filtering, and averaging methods to improve the signal-to-noise ratio or repetitive signals. Correlation and spectral analysis approaches to analysing signals are covered as well as methods to estimate and define unknown signals. Non-linear processing is introduced including the use of neural networks. The final chapter extends what the reader has learnt into the arena of multidimensional signals and data.
The aim of the book is not to be deeply rigorous mathematically but rather to provide full and practical explanation of the theories and concepts behind these processing techniques which are largely available today as software programs and packages.
Recent progress in the design and production of digital signal processing (DSP) devices has provided significant new opportunities to workers in the already extensive field of signal processing. It is now possible to contemplate the use of DSP techniques in cost-sensitive wide bandwidth applications, thereby making more effective use of the large body of available signal processing knowledge. Digital signal processing, long the province of telecommunications is, in both research and applications contexts, of growing importance in fields of medical signal analysis, industrial control (particularly robotics), in the analysis and synthesis of speech and in both audio and video entertainment systems. The growing demand for engineering skills in these areas has led to the writing of this book and the presentation of the material of the book at an lEE-sponsored Vacation School at the University of Leicester.
This book is different from others in the field in that it not only presents the fundamentals of DSP ranging from data conversion to z-transforms and spectral analysis, extending this into the areas of digital filtering and control, but also gives significant detail of the new devices themselves and how to use them. In addition to presenting the basic theory and describing the devices and how to design with them, the material is consolidated by extensive use of real examples in specific case studies.
The book is directed at readers with first degree level training in engineering, physical sciences or mathematics and with some understanding of electronics, and is appropriate for design engineers in industry, users of DSP devices in scientific research and in all technical development areas associated with the processing of signals for display, storage, transmission or control.

From fundamental concepts and procedures to recent technology advances in digital receivers, you get practical solutions to all your demanding wideband receiver problems. This hands-on reference is packed with 1,103 equations and 315 illustrations that support key topics covered throughout the book.
Foundations of Digital Signal Processing: Theory, algorithms and hardware design starts by introducing the mathematical foundations of DSP, assuming little prior knowledge of the subject from the reader, and moves on to discuss more complex topics such as Fourier, Laplace and digital filtering. It provides detailed information on off-line, real-time and DSP programming, and guides the reader through advanced topics such as DSP hardware design, FIR and IIR filter design and difference equation manipulation.
A CD accompanies the book. It provides the reader with programs that demonstrate equations discussed in the text and source codes to enable the reader to incorporate algorithms into their own DSP programs.
There is a growing interest in the development and deployment of surveillance systems in public and private locations. Conventional approaches rely on the installation of wide area CCTV (Closed Circuit Television), but the explosion in the numbers of cameras that have to be monitored, the increasing costs of providing monitoring personnel and the limitations that humans have to maintain sustained levels of concentration severely limit the effectiveness of these systems. Advances in information and communication technologies, such as computer vision for face recognition and human behaviour analysis, digital annotation and storage of video, transmission of video/audio streams over wired and wireless networks, can potentially provide significant improvements in this field.
The book consists of a coherent selection of extended versions of presentations made in two successful IEE symposia on Intelligent Distributed Surveillance Systems (IDSS). It surveys recent development in distributed intelligent surveillance systems and brings together the work of researchers and engineers, system integrators and managers of public and private organisations likely to use such systems.
This is the first book to discuss current and future applications of waveform diversity and design in subjects such as radar and sonar, communications systems, passive sensing, and many other technologies. Waveform diversity allows researchers and system designers to optimize electromagnetic and acoustic systems for sensing, communications, electronic warfare or combinations thereof. This book enables solutions to problems, explaining how each system performs its own particular function, as well as how it is affected by other systems and how those other systems may likewise be affected. It is an excellent standalone introduction to waveform diversity and design, which takes a high potential technology area and makes it visible to other researchers, as well as young engineers.
Brain-machine interfacing or brain-computer interfacing (BMI/BCI) is an emerging and challenging technology used in engineering and neuroscience. The ultimate goal is to provide a pathway from the brain to the external world via mapping, assisting, augmenting or repairing human cognitive or sensory-motor functions.
In this book an international panel of experts introduce signal processing and machine learning techniques for BMI/BCI and outline their practical and future applications in neuroscience, medicine, and rehabilitation, with a focus on EEG-based BMI/BCI methods and technologies. Topics covered include discriminative learning of connectivity pattern of EEG; feature extraction from EEG recordings; EEG signal processing; transfer learning algorithms in BCI; convolutional neural networks for event-related potential detection; spatial filtering techniques for improving individual template-based SSVEP detection; feature extraction and classification algorithms for image RSVP based BCI; decoding music perception and imagination using deep learning techniques; neurofeedback games using EEG-based Brain-Computer Interface Technology; affective computing system and more.
The contributors to Signal Traffic investigate how the material artifacts of media infrastructure--transoceanic cables, mobile telephone towers, Internet data centers, and the like--intersect with everyday life. Essayists confront the multiple and hybrid forms networks take, the different ways networks are imagined and engaged with by publics around the world, their local effects, and what human beings experience when a network fails.
Some contributors explore the physical objects and industrial relations that make up an infrastructure. Others venture into the marginalized communities orphaned from the knowledge economies, technological literacies, and epistemological questions linked to infrastructural formation and use. The wide-ranging insights delineate the oft-ignored contrasts between industrialized and developing regions, rich and poor areas, and urban and rural settings, bringing technological differences into focus.
Contributors include Charles R. Acland, Paul Dourish, Sarah Harris, Jennifer Holt and Patrick Vonderau, Shannon Mattern, Toby Miller, Lisa Parks, Christian Sandvig, Nicole Starosielski, Jonathan Sterne, and Helga Tawil-Souri.
The switched-current technique is heralding a new era in analogue sampled-data signal processing. Unlike switched-capacitor circuits, switched-current circuits do not require linear floating capacitors or operational amplifiers and they are giving a renewed impetus to mixed-signal VLSI on standard digital technology. Key analogue designers from industry and academia worldwide have contributed to this first, very timely book entirely devoted to switched current analogue signal processing.
The book introduces the basic switched-current technique, reviews the state-of-theart and presents practical chip examples. Numerous application areas are described, ranging from filters and data converters to image processing applications. It also gives a very comprehensive treatment of the fundamental principles of switched-current circuits and systems.
The material in this book will be of benefit to students, both undergraduate and postgraduate, and researchers and circuit designers in academia and the electronics industry.

Interest in the applications of ultrawideband (UWB) radar systems is increasing rapidly all over the world. This is evident from the number of monographs recently published on the subject and from the many papers presented at international conferences on the general problems involved in UWB radar and on its promising new applications. Conventional (classical) methods seem to have exhausted their potential and studies in the field are undergoing a profound change. This book presents some of the novel approaches to radar system analysis now being investigated.
A good source of information on UWB signals is their structural analysis in the time domain. This allows a greater understanding of the specific features of UWB radar systems, such as the properties of receiving and transmitting antennas, and various characteristics of near- and far-range target scattering fields. It is shown how the systematic application of numerical procedures can provide new results in the evaluation of UWB radar target responses.
The authors do not try to cover all of the possible solutions to the problem of multidimensional representation of target responses; rather they aim to give a general understanding of the techniques of confluent analysis, computer holography and adaptive synthesis of antenna apertures. These methods have great potential for solving conventional radar problems in target detection and recognition, and they are sure to stimulate the use of UWB signals in many fields such as subsurface probing and ecological monitoring.

Matsuo Sekine The Institution of Engineering and Technology, 1990 Library of Congress TK6580.S395 1990 | Dewey Decimal 621.3848
The material presented in this book is intended to provide the reader with a practical treatment of Weibull distribution as applied to radar systems.
Topics include general derivation of Weibull distribution, measurements of Webull-distributed clutter, comparison of Webull distribution with various distributions including Rayleigh, gamma, log-normal and k- distributions, constant false alarm rate (CFAR) detectors for Weibull clutter, non-parametric CFAR detectors, and signal detection in the time and frequency domains. In particular, the Akaike Information Criterion (AIC), which is a rigorously mathematical fit of the hypothetical distribution to the data, is emphasised.
This book is written primarily for radar engineers. It is hoped that it will also be of value to teachers and graduate students and of interest to all who are working with Weibull distribution in various fields.
