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.

Excerpt from The Measurement of Frequency and Frequency Stability of Precision Oscillators The specification and performance of precision oscillators is a very important topic to the owners and users of these oscillators. This paper presents at the tutorial level some convenient methods of measuring the frequencies and/or the frequency stabilities of precision oscillators - giving advantages and disadvantages of these methods. Conducting such measurements, of course, gives additional understanding into the performance of the given pair of oscillators involved. Further it is shown that by processing the data from the frequency measurements in certain ways, one may be able to state more general characteristics of the oscillators being measured. The goal in this regard is to allow the comparisons of different manufacturers' specifications and more importantly to help assess whether these oscillators will meet the standard of performance the user may have in'a particular application. The methods employed for measuring frequency are designed for state - of the-art oscillators, and an effort has been made to allow for fairly simple, inexpensive, and/or commonly available components to be used in the measurement systems. The method for measuring frequency stability is basically that recommended by the ieee subcommittee on Frequency Stability of the Technical Committee on Frequency and Time of the ieee Group on Instrumentation Measurement. Keywords: Accurate frequency measurement; Accurate time measurement; Frequency; Frequency stability; Frequency stability analysis; Models of frequency stability; Picosecond time difference measurements.
