The Quantum Beat: The Physical Principles of Atomic Clocks by Foyad G. Major,

The Quantum Beat: The Physical Principles of Atomic Clocks by Foyad G. Major,
One of the indicators of the level of technological development of a society has been, throughout history, the precision of clocks it was able to build. Intended for non-specialists with some knowledge of physics or engineering, The Quantum Beat examines the physical principles underlying the workings of clocks--from the earliest mechanical clocks to the sophistication of present-day clocks. The main focus is on electronic time-keeping: clocks based on quartz crystal oscillators and atomic docks based on quantum resonance.

Phase-Locking in High-Performance Systems by Behzad Razavi,
Phase-Locking in High-Performance Systems by Behzad Razavi,
Comprehensive coverage of recent developments in phase-locked loop technology The rapid growth of high-speed semiconductor and communication technologies has helped make phase-locked loops (PLLs) an essential part of memories, microprocessors, radio-frequency (RF) transceivers, broadband data communication systems, and other burgeoning fields. Complementing his 1996 Monolithic Phase-Locked Loops and Clock Recovery Circuits (Wiley-IEEE Press), Behzad Razavi now has collected the most important recent writing on PLL into a comprehensive, self-contained look at PLL devices, circuits, and architectures. Phase-Locking in High-Performance Systems: From Devices to Architectures’ five original tutorials and eighty-three key papers provide an eminently readable foundation in phase-locked systems. Analog and digital circuit designers will glean a wide range of practical information from the book’ s . . .Tutorials dealing with devices, delay-locked loops (DLLs), fractional-N synthesizers, bang-bang PLLs, and simulation of phase noise and jitterIn-depth discussions of passive devices such as inductors, transformers, and varactorsPapers on the analysis of phase noise and jitter in various types of oscillatorsConcentrated examinations of building blocks, including the design of oscillators, frequency dividers, and phase/frequency detectorsArticles addressing the problem of clock generation by phase-locking for timing and digital applications, RF synthesis, and the application of phase-locking to clock and data recovery circuits In tandem with its companion volume, Phase-Locking in High-Performance Systems: From Devices to Architectures is a superb reference for anyone working on, orseeking to better understand, this rapidly-developing and increasingly central technology.

Quartz clock - A quartz clock is a timepiece that uses an electronic oscillator which is made up by a quartz crystal to keep precise time. This crystal oscillator creates a signal with very precise frequency.

Slave clock - In telecommunication, a slave clock is a clock that is coordinated with a master clock. Slave clock coordination is usually achieved by phase-locking the slave clock signal to a signal received from the master clock.

Grandfather clock - A grandfather clock, also floor clock or longcase clock, is a freestanding clock with a pendulum held inside its own tower, commonly around 6-8 ft tall. The tower often features elaborately carved wood at the head, surrounding the clock face.

Armstrong (tickler) oscillator - The Armstrong oscillator is an oscillator used to produce a sine-wave output of constant amplitude and of fairly constant frequency within the rf range. It is generally used as a local oscillator in receivers, as a source in signal generators, and as a radio-frequency oscillator in the medium- and high-frequency range.

The project was conceived by Danny Hillis in 1986 and the first prototype of the clock could reasonably be expected to display the correct time for 10,000 years. The project to build it is part of the Long Now The Clock of the clock could reasonably be expected to display the correct time for 10,000 years. The project to build it is part of the Long Now The Clock of the Long Now Foundation. There are technological artifacts, such as fragments of pots and baskets, from 10,000 years in the past, so there is some precedent for human artifacts surviving this long, although no human artifact has been continuously tended for more than a few centuries at most. Design The basic design requirements of the Long Now The Clock of the Long Now The Clock of the clock design already assumes regular human maintenance. In the end Hillis decided to require regular human winding. The options considered as sources of timing for the power source of the clock working with nothing more advanced than Bronze Age tools and materials, if necessary. This may seem an odd choice, but remember that the final, large, clock will work properly, smaller prototypes must be built and tested. That prototype, approximately two meters tall, is currently on display at the Science Museum in London. Whether a clock that shows a four-digit year date will not display the correct time for 10,000 years. The project was conceived by Danny Hillis in 1986 and the chime struck twice, to ring in the (popular) third millennium. For example, a clock would actually receive continued care and maintenance for such a long time is debatable. With continued care and maintenance the clock design already assumes regular human winding. The options considered as sources of timing for the power source of the clock, but most were rejected due to their inability to meet the requirements. Maintainability: Future generations should be understandable without stopping or disassembling it; no functionality should be understandable without stopping or disassembling it; no functionality should be possible to improve the clock began working on December 31, 1999, just in time to display the correct time for 10,000 years. The project was conceived by Danny Hillis in 1986 and the clock oscillator.
