The Analogue-to-digital converter (ADC) is the most pervasive block in electronic systems. With the advent of powerful digital signal processing and digital communication techniques, ADCs are fast becoming critical components for system s performance and flexibility. Knowing accurately all the parameters that characterise their dynamic behaviour is crucial, on one hand to select the most adequate ADC architecture and characteristics for each end application, and on the other hand, to understand how they affect performance bottlenecks in the signal processing chain.

In this book, Grabe illustrates the breakdown of traditional error calculus in the face of modern measurement techniques. Revising Gauss error calculus ab initio, he treats random and unknown systematic errors on an equal footing from the outset. Furthermore, Grabe also proposes what may be called well defined measuring conditions, a prerequisite for defining confidence intervals that are consistent with basic statistical concepts. The resulting measurement uncertainties are as robust and reliable as required by modern-day science, engineering and technology."

Modulation Calorimetry reviews modulation techniques for measuring specific heat, thermal expansivity, temperature derivative of resistance, thermopower, and spectral absorptance. Owing to the periodic nature of the temperature oscillations, high sensitivity and excellent temperature resolution are peculiar to all these methods. The monograph presents the various methods of the modulation and of measuring the temperature oscillations. Important applications of the modulation techniques for studying physical phenomena in solids and liquids are considered in depth...

This book compares and offers a comprehensive overview of nine analytical techniques important in material science and many other branches of science. All these methods are already well adapted to applications in diverse fields such as medical, environmental studies, archaeology, and materials science. This clearly presented reference describes and compares the principles of the methods and the various source and detector types.

Physical processes, involving atomic phenomena, allow more and more precise time and frequency measurements. This progress is not possible without convenient processing of the respective raw data. The book describes the data processing at various levels: design of the time and frequency references, characterization of the time and frequency references, applications involving precise time and/or frequency references.The metrological properties stability, accuracy and reproducibility are defined and the processes leading to their characterization are shown. The various aspects of the...

Scientific research involving neutrons or synchrotron radiation is performed in large experimental installations at a few sites around the world. Taking full advantage of such techniques requires a wide range of specialized expertise not found in any university course. Therefore, there is a need for reference books and training courses to introduce young scientists to the underlying principles and methods.

Neutron and X-Ray Spectroscopy delivers an up-to-date account of the principles and practice of inelastic and spectroscopic methods available at neutron and...

It is for the first time that the subject of quantities and their respective units is dealt this much in detail, a glimpse of units of measurements of base quantities of length, time, mass and volume is given for ancient India, three and four dimensional systems of measurement units are critically examined, establishment of the fact that only four base units are needed to describe a system of units, the basics to arrive at the unit of a derived quantity are explained, basic, derived and dimensionless quantities including quantity calculus are introduced, life history of scientists...
