An in-depth look at the theory and applications of frequency stability An understanding of the acquisition of stable frequency is essential for anyone who needs to solve noise problems in wireless communications. This book offers a thorough introduction to the principles and applications of frequency stability, arming practicing engineers with the tools they need to minimize noise in systems and devices that affect everyday communications for millions of people. With an emphasis on both practical and scientific points of view, Frequency Stability: Introduction and Applications examines frequency and time fluctuations in resonators, as well as the stability of both standard and practical microwave oscillators. It explains noise properties of building circuit blocks, introducing time domain properties and how they relate to noise spectral densities. Including a special chapter devoted to the design and properties of phase locked loops—a crucial topic for frequency synthesizers—the book also: Examines in detail L/F noise, showing how power losses in the propagation material extend over a long period of time Covers sapphire, optoelectronics, MW, and ring oscillators with the discussion of noise in delay-line oscillators with lasers Offers an extended treatment of phase noise in semiconductors and amplifiers based on Van der Ziel investigations Emphasizes the modified Allan variance in the time domain, including exact computations Outlines the relationship between resonator frequency and output phase noises via the feedback theory Featuring numerous tables with actual data, Frequency Stability: Introduction and Applications is an invaluable guide for engineers wishing to rein in acoustic and electromagnetic interference in modern communications.

This book argues that only by reforming the international monetary system can we prevent financial crises in the future and the internationalization of the Renminbi, China's national currency, will be an important step in the process.Just as the old saying goes, 'An old building needs to be demolished before a new one can be erected in its place,' there will be no construction without destruction. The commencement of the dismantling of the old monetary system is also the beginning of the construction of the new one. Contrary to Western rhetoric, which portrays China as part of the cause of the recent financial crisis, the author contends that China is actually a victim of the current unjust international economic and monetary system. To address the imbalance and break the dollar-dominated international monetary system, the author calls for the internationalization of the Renminbi and diversification of the international monetary system.Written by one of the foremost financial practitioners in China, this book is thought-provoking and provides a unique Chinese perspective on how the international monetary system should be reformed, what the future system should look like and the role China should play in the process. It is a required reading for anyone interested in understanding China's own vision in its rise in the global political, economic and financial systems.

With the advent of integrated circuits (IC), digital systems havebecome widely used in modern electronic devices, includingcommunications and measurement equipment. Direct Digital FrequencySynthesizers (DDS) are used in communications as transmitterexciters and local oscillators in receivers. The advantages aresuperior frequency stability, the same as that of the driving clockoscillator, and short switching times. The difficulties are loweroutput frequencies and rather large spurious signals. Compiled for practicing engineers who do not have theprerequisite of a specialist's knowledge in Direct DigitalFrequency Synthesizers (DDS), this collection of 40 importantreprinted papers and 9 never-before published contributionspresents a comprehensive introduction to DDS properties and a clearunderstanding of actual devices. The information in this volume canlead to easier computer simulations and improved designs. Featured topics include: * Discussion of principles and state of the art of wide-rangeDDS * Investigation of spurious signals in DDS * Combination of DDS with Phase Lock Loops (PLL) * Examination of phase and background 'noise' in DDS * Introduction to Digital to Analog Conversion (DAC) * Analysis of mathematics of quasiperiodic omission ofpulses DDFS can also serve as a textbook for students seeking essentialbackground theory.

Quartz, zeolites, gemstones, perovskite type oxides, ferrite, carbon allotropes, complex coordinated compounds and many more -- all products now being produced using hydrothermal technology. Handbook of Hydrothermal Technology brings together the latest techniques in this rapidly advancing field in one exceptionally useful, long-needed volume.The handbook provides a single source for understanding how aqueous solvents or mineralizers work under temperature and pressure to dissolve and recrystallize normally insoluble materials, and decompose or recycle any waste material. The result, as the authors show in the book, is technologically the most efficient method in crystal growth, materials processing, and waste treatment. The book gives scientists and technologists an overview of the entire subject including: À Evolution of the technology from geology to widespread industrial use. À Descriptions of equipment used in the process and how it works.À Problems involved with the growth of crystals, processing of technological materials, environmental and safety issues.À Analysis of the direction of today's technology. In addition, readers get a close look at the hydrothermal synthesis of zeolites, fluorides, sulfides, tungstates, and molybdates, as well as native elements and simple oxides. Delving into the commercial production of various types, the authors clarify the effects of temperature, pressure, solvents, and various other chemical components on the hydrothermal processes. - Gives an overview of the evolution of Hydrothermal Technology from geology to widespread industrial use - Describes the equipment used in the process and how it works - Discusses problems involved with the growth of crystals, processing of technological materials, and environmental and safety issues

A biosensor is a detecting device that combines a transducer with a biologically sensitive and selective component. Biosensors can measure compounds present in the environment, chemical processes, food and human body at low cost if compared with traditional analytical techniques. This book covers a wide range of aspects and issues related to biosensor technology, bringing together researchers from 19 different countries. The book consists of 27 chapters written by 106 authors and divided in three sections: Biosensors Technology and Materials, Biosensors for Health and Biosensors for Environment and Biosecurity.
