Digital Signal Filtering, Analysis and Restoration

Tue, 12 Jun 2018 01:19:30 GMT

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.

Selected Topics in Advanced Solid State and Fibre Optic Sensors

Tue, 12 Jun 2018 00:59:44 GMT

New techniques and technologies for sensors are developing fast and being applied in a wide range of fields for measurement and instrumentation, both for research and commercial purposes. This book aims to provide advanced students and practising engineers with a selective tour of highlights in the topical field of sensors for measurement. The authors provide descriptions of the operation, characteristics and applications of the sensors on which they work, together with recent advances and prospects for the future. The chapters cover both fibre optic and solid state sensing, applied across a wide range of applications.

Although primarily aimed at graduate-level students and engineers, the depth of coverage of each sensor type is such that the book will be useful to undergraduates seeking to supplement their knowledge for courses on sensors, measurement and instrumentation.

Restoring Baird's Image

Tue, 12 Jun 2018 00:34:44 GMT

John Logie Baird, Britain's foremost television pioneer, experimented with video recording onto gramophone discs in the late 1920s. Though unsuccessful at the time, his experiments resulted in several videodiscs, some 25 years before the videotape recorder became practical. These videodiscs - called Phonovision - remained neglected over the decades, considered by experts as unplayable.

In the early 1980s, the author sought out and restored the surviving Phonovision discs. Using computer-based techniques in an investigation reminiscent of an archaeological dig, the author has not only revealed the images on the discs but also uncovered details of how the recordings were made. The Phonovision discs have now become recognised as one of Baird's most important legacies.

In 1996 and 1998, amateur 'off-air' recordings of the BBC's 30-line Television Service (1932-35) were found, giving us our first view of what viewers were then watching. The author's restoration overturns established views on mechanically scanned television, providing us today with a true measure of Britain's heritage of television programme-making before electronic television.

As well as helping to explain a poorly understood and complex period in television's history, this unique book, heavily illustrated with previously unpublished or rarely-seen historic photographs restored by the author, sheds light on the achievements of Baird, the development of video recording and the definition and invention of television itself.

The Life and Times of A.D. Blumlein

Tue, 12 Jun 2018 00:30:55 GMT

Alan Dower Blumlein was a genius and has been described as the greatest British electronics engineer of the twentieth century. Although he was tragically killed at the age of 38, he contributed enormously to the fields of telephony and electrical measurements, monophonic and stereophonic recording and reproduction, high definition television, electronics, antennas and cables, and radar systems of various types. His accidental death in June 1942 was described by an Air Chief Marshal as 'a catastrophe', and the Secretary of State for Air said that 'it would be impossible to over-rate the importance of the work on which [Blumlein was] engaged': his loss was a 'national disaster'. He was responsible for saving many thousands of lives during the Second World War, and his endeavours in peacetime led to pleasure being given to millions of people.

This meticulous, extensively researched and well-referenced book presents a balanced account of the life and times of a brilliant engineer. It is certain to be the major biographical source on Blumlein for all historians of technology and science.

John Logie Baird

Tue, 12 Jun 2018 00:30:22 GMT

Professor Russell Burns attempts to offer a balanced biography of one of the twentieth century's outstanding inventors, published to coincide with the 75th anniversary of Baird's first public demonstration of a rudimentary television system. The author's meticulous treatment is based on primary source documents although many personal recollections are included to add humour, colour and context. A great deal of material regarding Baird's business partnerships in the early 1920s has only recently become available to researchers and is covered here for the first time.

Baird is credited in Britain and elsewhere as the inventor of television, realising a quest which for fifty years had engaged the attention of inventors, scientists and engineers. When he started work he had no regular income, no research experience and no laboratory or workshop, his work had no funding or commercial sponsorship, and initially he had no expert help. Having demonstrated a rudimentary system in early 1926 he then developed many other aspects of television and aspired to launch a low-definition television broadcasting service. To raise capital he entered various business partnerships. Holding many patents, he could have retired wealthy but he chose instead to develop his ideas further, focusing on cinema, colour and stereoscopic television, so that when he died he left only £7000.

The book illuminates Baird's life and work in many interesting ways. For example, how did Baird's technical strategy and development compare with the work undertaken in industrial laboratories? How did his development policy compare with the development of wireless by Marconi? Was his 'invention' in 1925 really outstanding?

Overvoltage Protection of Low Voltage Systems, 2nd Edition

Mon, 11 Jun 2018 23:43:47 GMT

This book surveys some of the techniques available to protect low-voltage electrical and electronic equipment and systems from lightning strikes and other power surges. The book examines the basic discharge processes in air and their effects, through transient electromagnetic field generation and interaction with overhead lines and underground cables. Attention is paid to the use of models for lightning protection and the book focuses on protection techniques based on modelled lightning protection zones. This is then logically developed in a major section on the practical components and applications of protective measures and systems, as well as testing techniques. These are placed in the context of current IEC and VDE standards. The book is highly illustrated with a vast number of photographs as well as system diagrams and tabular matter.

Embedded Generation

Mon, 11 Jun 2018 23:24:47 GMT

The use of combined heat and power (CHP) plants and renewable energy sources reduces the amount of greenhouse gases released into the atmosphere and helps to alleviate the consequent climate change. The policies of many governments suggest that the proportion of electrical energy produced by these sources will increase dramatically over the next two decades. Unlike traditional generating units, these new types of power plant are usually 'embedded' in the distribution system or 'dispersed' around the network. As a result, conventional design and operating practices are no longer applicable; for example, power protection principles have to be revised and complex economic questions need to be resolved.

This book, intended for both students and practising engineers, addresses all the issues pertinent to the implementation of embedded generation. Much of the material was originally developed for the UMIST MSc/CPD course in Electrical Power Engineering so there is a strong tutorial element. However, since this subject is evolving very rapidly, the authors also discuss the technical and commercial consequences of the very high penetration of embedded generation that are to be expected in the years ahead.

Small Signal Microwave Amplifier Design

Mon, 11 Jun 2018 22:55:12 GMT

This book explains techniques and examples for designing stable amplifiers for high-frequency applications, in which the signal is small and the amplifier circuit is linear. An in-depth discussion of linear network theory provides the foundation needed to develop actual designs. Examples throughout the book will show you how to apply the knowledge gained in each chapter leading to the complex design of low noise amplifiers. Exercises at the end of each chapter will help students to practice their skills. The solutions to these design problems are available in an accompanying solutions booklet (Small Signal Microwave Amplifier Design: Solutions).

Ridge Waveguides and Passive Microwave Components

Mon, 11 Jun 2018 22:50:25 GMT

The ridge waveguide, which is a rectangular waveguide with one or more metal inserts (ridges), is an important transmission line in microwave engineering, through which many passive components can be achieved. As such it is a well-established and widely used element in commercial electronics and communications devices. This book collects together much of the work of Professor Helszajn, an international authoriy in the field, and will enable the reader to have direct access to this material without need for exhaustive search of research papers. Generously illustrated, it is likely to become the definitive reference source on this topic. The book includes closed-form and finite element calculations of the propagation constant, attenuation and mode spectrum for the ridge waveguide, as well as power-current and power-voltage definitions of impedance. Circular polarisation is also treated. Propagation properties where the waveguide has a dielectric filler are calculated. The treatment is then extended to more complex designs, including quadruple ridge waveguides with and without a gyromagnetic filler. The text includes descriptions of many of the passive devices which can be realised using these waveguides, including isolators, phase shifters and circulators. A treatment of the finline waveguide is included as its geometry is closely related to that of the ridge waveguide, leading to components such as the 3-port finline calculator.

Parabolic Equation Methods for Electromagnetic Wave Propagation

Mon, 11 Jun 2018 22:36:07 GMT

This book is the first to present the application of parabolic equation methods in electromagnetic wave propagation. These powerful numerical techniques have become the dominant tool for assessing clear-air and terrain effects on radiowave propagation and are growing increasingly popular for solving scattering problems.

The book gives the mathematical background to parabolic equation modelling and describes simple parabolic equation algorithms before progressing to more advanced topics such as domain truncation, the treatment of impedance boundaries and the implementation of very fast hybrid methods combining ray-tracing and parabolic equation techniques. The last three chapters are devoted to scattering problems, with application to propagation in urban environments and to radar cross section computation.

This book will prove useful to scientists and engineers who require accurate assessment of diffraction and ducting on radio and radar systems. Its self-contained approach should also make it particularly suitable for graduate students and other researchers interested in radiowave propagation scattering.

Power Plant Control and Instrumentation

Mon, 11 Jun 2018 21:33:58 GMT

This book provides a practical and comprehensive analysis of control systems for boilers and HRSGs (heat-recovery steam generators) in a variety of applications from waste-to-energy plants through to combined-cycle gas-turbine power stations (CCGTs).

It describes process transmitters, advanced DCS configurations and final elements such as control valves and dampers. Basics such as methods of connecting instruments to the process are explained while more advanced discussions of the design features of distributed control systems are also included. At every stage, emphasis is given to the complex, multivariable, interactive nature of steam-raising plant and to the importance of dealing with the problems that result.

Chapters are devoted to the application of modern nomenclature systems and to the documentation required to ensure that the equipment and systems meet all the requirements of performance, accuracy, safety and maintainability.

This book will provide invaluable practical guidance for systems engineers, operators, maintenance staff and specifiers of power plant control and instrumentation (C&I) systems.

Flight Control Systems

Mon, 11 Jun 2018 21:18:22 GMT

A complete reference on modern flight control methods for fixed-wing aircraft, this authoritative book includes contributions from an international group of experts in their respective specialised fields, largely from industry. Split into two parts, the first section of the book deals with the fundamentals of flight control systems design, while the second concentrates on genuine applications based on the modern control methods used in the latest aircraft.

It is assumed that the reader will have some knowledge of classical control. The book builds upon the foundations laid by standard texts on flight control so that the reader will gain a good background in current industrial practice and be in a position to benefit from more specialised reading. Its prime aim is to bridge the gap between academic research and real-world applications in the area and its emphasis on practical approaches will make it particularly suitable for:

practising engineers who are relatively new to the aviation industry and require a consolidated approach to the different aspects of flight control
postgraduate students in strategic or applied research
final stage undergraduates.
