This text on precision frequency measurement and its key enabling techniques includes reviews written by some of the most experienced researchers in their respective fields. This text should prove useful to researchers just entering the field of frequency metrology and standards, or equally well to the experienced practitioner.

The output signal controls a VCO. When it is phase locked, the frequency f2 becomes equal to f1 and fl = f2 + Af becomes f = f2 + 10Af. Multiplication by 10” is achieved by using n successive states. Difference-multiplier noise.

Periodical phenomena or, more precisely, quasiperiodical phenomena, occupy a central position in physics. For a long time, their most important parameter has been their period. However, nowadays, we are much more interested in their frequency, and the many reasons for this are discussed in this book. Throughout history, evaluations of time have been based on periodical phenomena such as the apparent motion of the Sun. Indeed, the oldest unit of time is the day. The apparent motion of the Moon and of the celestial sphere, including changes in the appearance of the former, provided longer units, namely, week, month and year. All these periodical phenomen- the natural clocks - were obviously well suited to the observation and prediction of the evolution of nature with its seasonal rhythm. The gnomon and the clepsydra gave reasonably precise subdivisions of the day that could be used in timing human activities, so long as they were mostly agricultural. The invention of the pendulum and of balance wheel clocks marked the dawn of industrial civilisation, which soon de manded measurements of time with ever increasing precision over shorter and shorter periods.

This is the fifth in a series initiated in 1989 by the International Commission for Optics (ICO). These books, which are published every three years, highlight the advances in optics that are underway at the time of their publication. These are a collection of significant contributions from leading scientists and engineers throughout the world. It shows the diverse role optics play in modern society, with optics now taking its place along with mechanical, thermal, electrical and electronic options, in order to bring solutions. The world is coming to recognize the ubiquitous nature of optics and its primarily enabling role in our everyday world.

Noise is ubiquitous in nature and in man-made systems. Noise in oscillators perturbs high-technology devices such as time standards or digital communication systems. The understanding of its algebraic structure is thus of vital importance. The book addresses both the measurement methods and the understanding of quantum, 1/f and phase noise in systems such as electronic amplifiers, oscillators and receivers, trapped ions, cosmic ray showers and in commercial applications. A strong link between 1/f noise and number theory is emphasized. The twenty papers in the book are comprehensive versions of talks presented at a school in Chapelle des Bois (Jura, France) held from April 6 to 10, 1999, by engineers, physisicts and mathematicians.
