Clock synchronization — is a problem from computer science and engineering which deals with the idea that internal clocks of several computers may differ. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by … Wikipedia
Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… … Wikipedia
Phase response curve — A phase response curve (PRC) illustrates the transient change in the cycle period of an oscillation induced by a perturbation as a function of the phase at which it is received. PRCs are used in various fields; examples of biological oscillations … Wikipedia

Clock of the Long Now — The first prototype, on display at the Science Museum in London. The Clock of the Long Now, also called the 10,000 year clock, is a proposed mechanical clock designed to keep time for 10,000 years. The project to build it is part of the Long Now… … Wikipedia
Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… … Wikipedia
Phase Frequency Detector — A phase frequency detector, in electronics, is a device which compares the phase of two input signals. It has two inputs which correspond to two different input signals, usually one from a voltage controlled oscillator (VCO) and another from some … Wikipedia
Speaking clock — A speaking clock service is used by people who wish to know the correct and accurate time. Speaking clock services are most commonly accessed by telephone.The format of the service is somewhat similar to those in radio time signal services. Every … Wikipedia
