Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Excerpt from Standard Time and Frequency: Its Generation, Control, and Dissemination by the National Bureau of Standards This paper describes some of the current activities of the Time and Frequency Division of the nbs. These include the generation of the computed nbs time scales, the control of working clocks, and the use of these clocks in coordination efforts with other standards laboratories. The coordination of the Fort Collins site clocks and frequency standards, the measurement and control of LE (and vlf) radiated phase, and the method of coordination of the Fort Collins master clock with that of nbs Boulder are also described. Additional information on the broadcasts is published annually in nbs Special Publication 236, available upon request from the Frequency - Time Broadcast Services Section National Bureau of Standards, Boulder, CO 80302.

The document is a tutorial Monograph describing various aspects of time and frequency (T/F). Included are chapters relating to elemental concepts of precise time and frequency; basic principles of quartz oscillators and atomic frequency standards; historical review, recent progress, and current status of atomic frequency standards; promising areas for developing future primary frequency standards; relevance of frequency standards to other areas of metrology including a unified standard concept; statistics of T/F data analysis coupled with the theory and construction of the NBS atomic time scale; an overview of T/F dissemination techniques; and the standards of T/F in the USA. The Monograph addresses both the specialist in the field as well as those desiring basic information about time and frequency. The authors trace the development and scope of T/F technology, its improvement over periods of decades, its status today, and its possible use, applications, and development in days to come.
