The Ondes Martenot is one of the precursors of electronic musical instruments, and is today considered, with the desire for a return to analogue, as a cult instrument. This book, which is the result of several years of research, sheds light on the intrinsic functioning of the Ondes Martenot. Based on the study of numerous prototypes, the authors trace the historical evolution of the different techniques used: additive, multiplicative and relaxation syntheses. Often, the analysis of the functioning of these instruments demonstrates atypical technological choices, underpinned by a logic that places artistic creation at the forefront. Several models and simulations are built, so as to understand the functioning of each of the different sub-assemblies (keyboard, ribbon, intensity key, timbre filter...). At the end of the book, the complete construction of an Onde (copy of model no. 208) is described in detail. This practical realization of a facsimile is an opportunity to explore the knowhow of the electronic luthier Maurice Martenot.

Many instrumentation engineers and scientists often deal with analog electronic issues when approaching delicate measurements. Even if off-the-shelf measuring solutions exist, comprehension of the analog behavior of the measuring system is often a necessity. This book provides a concise introduction to the main elements of a low frequency analog acquisition chain. It aims to be sufficiently general to provide an introduction, yet specific enough to guide the reader through some classical problems that may be encountered in the subject. Topics include sensors, conditioning circuits, differential and instrumentation amplifiers, active filters (mainly for anti-aliasing purposes) and analog to digital converters. A chapter is devoted to an introduction to noise and electronic compatibility. This work is intended for people with a general background in electronics and signal processing, who are looking for an introduction to classical electronic solutions employed in measuring instruments involving low frequency analog signal processing.

Over the last 60 years, electronics has undergone important and rapid developments. This has generated a large range of theoretical and practical notions. This book presents a comprehensive treatise on the evolution of electronics and allows the reader to grasp both the fundamental concepts and the associated practical applications through examples and exercises. Following on from Volume 1, which studied elementary devices, their electrical models and basic functions, Volume 2 was devoted to linear and stationary systems in the continuous-time regime. This third volume deals with the properties of discrete-time and quantized level systems over two chapters. The first presents an analysis of sampled signals and systems, with applications on switched capacitors circuits, analog and digital phase locked loops, frequency synthesis and filters characterized by either finite or infinite impulse response. Most tools are useful to elucidate the properties of both analog and digital systems. The second chapter focuses on the properties of analog-to-digital and digital-to-analog converters. Various principles that are used to perform these conversions are described. Finally, a large section is devoted to sigma-delta converters. Throughout this whole chapter, the signal-to-noise ratio, which is a central issue in these quantized level systems, is analyzed and discussed. Both chapters are followed by useful exercises which illustrate the general principles addressed. The exercises further build on the material covered in the chapters, particularly that which may not have been covered in detail.

The improvement of energy efficiency in electronics and computing systems is currently central to information and communication technology design; low-cost cooling, autonomous portable systems and functioning on recovered energy all need to be continuously improved to allow modern technology to compute more while consuming less. This book presents the basic principles of the origins and limits of heat dissipation in electronic systems. Mechanisms of energy dissipation, the physical foundations for understanding CMOS components and sophisticated optimization techniques are explored in the first half of the book, before an introduction to reversible and quantum computing. Adiabatic computing and nano-relay technology are then explored as new solutions to achieving improvements in heat creation and energy consumption, particularly in renewed consideration of circuit architecture and component technology. Concepts inspired by recent research into energy efficiency are brought together in this book, providing an introduction to new approaches and technologies which are required to keep pace with the rapid evolution of electronics.

The omnipresence of electronic devices in our everyday lives has been accompanied by the downscaling of chip feature sizes and the ever increasing complexity of digital circuits. This book is devoted to the analysis and design of digital circuits, where the signal can assume only two possible logic levels. It deals with the basic principles and concepts of digital electronics. It addresses all aspects of combinational logic and provides a detailed understanding of logic gates that are the basic components in the implementation of circuits used to perform functions and operations of Boolean algebra. Combinational logic circuits are characterized by outputs that depend only on the actual input values. Efficient techniques to derive logic equations are proposed together with methods of analysis and synthesis of combinational logic circuits. Each chapter is well structured and is supplemented by a selection of solved exercises covering logic design practices.

This book addresses the difficulty of obtaining a quality solution, that is, pre optimal or even optimal, in a reasonable time from a central processing unit (CPU). As polynomial problems can be treated by exact methods, the problem posed concerns non-polynomial problems, for which it is necessary to develop efficient algorithms based on heuristics or meta-heuristics. Chapter 3 of this book demonstrates how to develop such algorithms, which are characterized by: an initialization of argued solutions (sometimes, the global optimum can be obtained from such an initialization); a non-random generation of solutions (to avoid generating the same solution several times, or even generating solutions that cannot be achieved); avoidance of being trapped by a local optimum; good use of CPU time by reducing the size of the space of solutions to be explored (which is often very large for such problems) without compromising the quality of the solution; plus a reasoned displacement from one solution to another, to improve the quality of the solution as the processing is carried out. These aspects are applied to concrete applications in the design of integrated circuits and systems at various levels. To do this and to help the reader better understand this problem, Chapters 1 and 2 present basic notions on computational complexity, and the design of integrated circuits and systems.
