Download or read book New Techniques for Measurement and Tracking of Phase and Frequency written by Martin Terence Hill and published by . This book was released on 1997 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An implementation of the new system is presented which employs the frequency measurement technique described above. This implementation is characterized by very precise centre frequency, high phase noise suppression, and can be built almost entirely in digital integrated circuit technology. The new system is experimentally demonstrated in some typical applications. The techniques presented in this thesis provide improvements of several orders of magnitude in the ability of systems implemented in digital integrated circuit technology to: Measure and control phase and frequency of narrow band signals; Implement high performance phase tracking systems.

Download or read book A Low Frequency Phase Shift Method written by Ronnie Carroll McMillan and published by . This book was released on 1969 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The phase shift method of measuring atomic lifetimes is particularly useful because it allows us to make measurements in the steady state mode instead of in the transient mode. High frequency phase shift techniques cause many problems. The equipment, which was designed and built to make low frequency phase shift techniques possible, is shown schematically and discussed. The new experimental techniques employed in our apparatus are a phase multiplier and a unique method of using a photomultiplier as a mixer. In the photomultiplier the final dynode is used as the grid of a triode. The next to the last dynode may be thought of as the cathode of a triode normally used as a mixer. Using the photomultiplier in this fashion, we have a low noise, extremely efficient mixer. The phase multiplier is essential to accurately measure small phase angles. The problems of high frequency techniques are cited and references given. The speed of light was measured as a test of the equipment. The experimental values resulted in a .95 confidence interval containing the generally accepted value of the speed of light in air. The average value measured was (2.937 ± .033) x 108 meters per second, where .033 is the standard deviation for 48 trials. This average value represents an error of 1.61%. From the results we have established the feasibility of this low frequency method of measuring atomic lifetimes"--Abstract, leaves [i-ii].

Download or read book Optimizing and Measuring Smart Grid Operation and Control written by Recioui, Abdelmadjid and published by IGI Global. This book was released on 2020-11-13 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart grid (SG), also called intelligent grid, is a modern improvement of the traditional power grid that will revolutionize the way electricity is produced, delivered, and consumed. Studying key concepts such as advanced metering infrastructure, distribution management systems, and energy management systems will support the design of a cost-effective, reliable, and efficient supply system, and will create a real-time bidirectional communication means and information exchange between the consumer and the grid operator of electric power. Optimizing and Measuring Smart Grid Operation and Control is a critical reference source that presents recent research on the operation, control, and optimization of smart grids. Covering topics that include phase measurement units, smart metering, and synchrophasor technologies, this book examines all aspects of modern smart grid measurement and control. It is designed for engineers, researchers, academicians, and students.

Download or read book Dynamic Measurement of Phase Shift and Amplitude written by John R. Kay and published by . This book was released on 1964 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test procedures and techniques were investigated for swept frequency measurements of phase and amplitude characteristics of microwave amplifiers and related components, as functions of both time and frequency. Techniques are applicable to production line testing where test time must be minimized but accuracy must be maintained. 2data are accurate and comprehensive over a broad frequency range. A reflectometer system is used for swept frequency gain measurements. A commercially available phase test set is used for swept frequency phase measurements. (Author).

Download or read book Chromaticity Tracking Using a Phase Modulation Technique written by and published by . This book was released on 2007 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the classical chromaticity measurement technique, chromaticity is measured by measuring the change in betatron tune as the RF frequency is varied. This paper will describe a novel way of measuring chromaticity: we will phase modulate the RF with a known sine wave and then phase demodulate the betatron frequency. The result is a line in Fourier space which corresponds to the frequency of our sine wave modulation. The peak of this sine wave is proportional to chromaticity. For this technique to work, a tune tracker PLL system is required because it supplies the betatron carrier frequency. This method has been tested in the Tevatron and we will show the results here.
