Available in PDF, EPUB and Kindle. Book excerpt: Since the previous Symposium, several exciting new developments and advances have occurred in the field of frequency standards and metrology. These include the first results on the long-tenn stability of a millisecond Pulsar, for which data 14 integrated over several years now show a stability of around 10- . Improvements in the understanding of various biases in Cesium beam standards promise accuracies in the low 14s for primary standards and in the low 13s for short commercial tubes, for which long tenn stabilities in low 14s have already been shown to be obtainable by accuracy improvement. Beams using optical pumping for state selection and for detection have been operated with excellent results, and more are being realized. Other new frequency standards which have appeared include a macroscopic rf trap with Mercury ions, which perfonns in the low 15s in one day, the sub millimeter metastable Magnesium beam, which has shown a short tenn stability 19 in the low 12s in one second and promises an accuracy of 10- , and the cold Hydrogen masers, which have such high stabilities that they cannot be measured with existing local oscillators. Prospects for future developments include laser manipulation of neutrals and spectroscopy of single ions at rest in a trap. Both these groups of techniques have great potential for unprecedented accuracy and short-and long-tenn stability, and new superior frequency standards are expected to be realizable in this way in the not too distant future.

This book was released on 2007-05-24 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. This book describes the data processing at various levels: design of the time and frequency references, characterization of the time and frequency references, and applications involving precise time and/or frequency references.

Download or read book Microwave and Wireless Synthesizers written by Ulrich L. Rohde and published by John Wiley & Sons. This book was released on 1997-08-25 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, great strides have been made in the technology of microwave oscillators and synthesizers, with digital frequency synthesizers in particular attracting much attention. These synthesizers are now being used in virtually all modern signal generators and radio communication equipment. Until now, however, detailed information about their design has been hard to come by-much of it scattered through journal articles-and most books on the subject have taken a primarily theoretical approach. Enter Microwave and Wireless Synthesizers-the first book to emphasize both practical circuit information from RF to millimeter-wave frequencies and up-to-date theory. Based on course material taught by author Ulrich L. Rohde at George Washington University and recent work done by the author at Compact Software, Inc. and Synergy Microwave Corporation, this volume is a complete revision and update of Rohde's landmark text, Digital PLL Frequency Synthesizers: Theory and Design. While it provides all the necessary theory and formulas, it also offers an in-depth look at the practical side of the phase-lock loop (PLL) in synthesizers-including special loops, loop components, and practical circuits-material that is not available in any other book. Rohde explains loop fundamentals, demonstrates the linear approach to oscillator phase noise, discusses the digital direct synthesizer technique, addresses low noise oscillator design, and provides insight into the role and design of crystal oscillators, mixers, phase/frequency discriminators, wideband high-gain amplifiers, programmable dividers, and loop filters. He goes on to cover conventional multiloop synthesizers and survey existing state-of-the-art microwave synthesizer applications. Extensive appendices review the mathematics of useful functions and various applications, including even the complex nonlinear theory of noise in large signal systems such as mixers and oscillators. Microwave and Wireless Synthesizers allows anyone with a PC running either Windows 3.11 or Windows NT to explore real-world design. It uses programs for the solution of digital phase-lock loop systems, tabulates the results, and shows how Bode diagrams are determined by the computer's graphic capabilities. It also includes examples using commercially available linear and nonlinear CAD programs to provide accurate evaluation and optimization of oscillators and other useful circuits and many practical charts. For companies involved in test and communication equipment, this book reduces design and research costs by providing a large number of proven circuits and expediting the design process. It is also an outstanding senior/graduate level textbook for electrical engineering students and an invaluable resource for practicing engineers, senior engineers, and managers who would like to be able to evaluate new trends and techniques in the field.
