Download or read book Externally Compensated Crystal Oscillator ECXO Study written by O. J. Baltzer and published by . This book was released on 1984 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this contract was an investigation and exploratory development of an externally compensated crystal oscillator (EXCO) in which frequency-temperature compensation of the C-mode frequency of an SC-cut quartz crystal is achieved by utilizing the concurrent B-mode frequency as a highly sensitive digital temperature sensor. The digitized B-mode output, used in conjunction with a microcomputer and a stored frequency/temperature look-up table or a suitable compensation algorithm, is able to provide precise and accurate clock corrections over a much wider range than that possible with a conventional TCXO oscillator (a temperature compensated oscillator which employs a voltage-variable capacitor for direct oscillator frequency control).

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is the development of a high-stability temperature compensated crystal oscillator (HSTCXO), capable of being produced in quantity for use in advanced SSB communications equipment. This report discusses progress in the second period, including additional retrace data on the frequency-temperature characteristics of crystals, the construction and coarse compensation of two HSTCXO models, and the fabrication and satisfactory test of MOS chips designed in the first period.

This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystal oscillators have been in use now for well over SO years-one of the first was built by W. G. Cady in 1921. Today, millions of them are made every year, covering a range of frequencies from a few Kilohertz to several hundred Mega hertz and a range of stabilities from a fraction of one percent to a few parts in ten to the thirteenth, with most of them, by far, still in the range of several tens of parts per million.Their major application has long been the stabilization of fre quencies in transmitters and receivers, and indeed, the utilization of the frequency spectrum would be in utter chaos, and the communication systems as we know them today unthinkable,'without crystal oscillators. With the need to accommodate ever increasing numbers of users in a limited spectrum space, this traditional application will continue to grow for the fore seeable future, and ever tighter tolerances will have to be met by an ever larger percentage of these devices.
Download or read book High Stability Temperature Compensated Crystal Oscillator Study written by Alan B. Mroch and published by . This book was released on 1976 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program is the further development of a high stability temperature compensated crystal oscillator (HSTCXO) initially developed under contract DAAB07-71-C-0136. This HSTCXO is digitally compensated and is intended for use as a reference frequency source in advanced tactical communications systems. The program is to include detailed investigations into critical areas of size reduction, compensation simplification, and performance improvement. Five advanced exploratory models of the digitally compensated HSTCXO are to be delivered.
Download or read book Practical Oscillator Handbook written by Irving Gottlieb and published by Elsevier. This book was released on 1997-06-12 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oscillators have traditionally been described in books for specialist needs and as such have suffered from being inaccessible to the practitioner. This book takes a practical approach and provides much-needed insights into the design of oscillators, the servicing of systems heavily dependent upon them and the tailoring of practical oscillators to specific demands. To this end maths and formulae are kept to a minimum and only used where appropriate to an understanding of the theory. Once grasped, the theory of the general oscillator is easily put into practical use in actual oscillators. The final two chapters present a collection of oscillators from which the practising engineer or the hobbyist can obtain useful guidance for many kinds of projects. Irving Gottlieb is a leading author of many books for practising engineers, technicians and students of electronic and electrical engineering. First Newnes title by this best-selling author Clarity and crispness in an often obscure field
Download or read book Research Work for Frequency Temperature Compensation Techniques for Quartz Crystal Oscillators written by and published by . This book was released on 1964 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to evolve a practical approach to the temperature compensation of quartz crystal oscillators. The study will be concentrated on a nominal frequency of five megacycles, but will be generally applicable to AT cut quartz crystals of from 1 to 20 megacycles. The use of graphical analysis for TCXO design is discussed. The results of this investigation show that a graphical analysis will not be useable for very accurate compensation because of resolution and parameters that cannot be taken into account with graphs. The techniques for determining compensation networks are discussed. A new technique is described where diodes are used in conjunction with thermistor-resistor networks. The 5 x 10 to the minus 8th power, Group III, TCXO's are discussed. Results of the first compensation attempts are given. The compensation networks and techniques used are presented. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: "The impact of technology on society is clear and unmistakeable. The influence of society on technology is more subtle. The 13 essays in this book have been written by a diverse group of scholars united by a common interest in creating a new field - the sociology of technology. They draw on a wide array of case studies - from cooking stoves to missile systems, from 15th-century Portugal to today's Al labs - to outline an original research program based on a synthesis of ideas from the social studies of science and the history of technology. Together they affirm the need for a study of technology that gives equal weight to technical, social, economic, and political questions"--Back cover.
