  2. Clock drift - Wikipedia

    en.wikipedia.org/wiki/Clock_drift

    Even the Earth's rotation rate has more drift and variation in drift than an atomic clock due to tidal acceleration and other effects. The principle behind the atomic clock has enabled scientists to re-define the SI unit second in terms of exactly 9 192 631 770 oscillations of the caesium-133 atom. The precision of these oscillations allows ...

  3. Clock synchronization - Wikipedia

    en.wikipedia.org/wiki/Clock_synchronization

    Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift , caused by clocks counting time at slightly different rates.

  4. Bit slip - Wikipedia

    en.wikipedia.org/wiki/Bit_slip

    In digital transmission, bit slip is the loss or gain of a bit or bits, caused by clock drift – variations in the respective clock rates of the transmitting and receiving devices. One cause of bit slip is overflow of a receive buffer that occurs when the transmitter's clock rate exceeds that of the receiver.

  6. Drift (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Drift_(telecommunications)

    In telecommunications, a drift is a comparatively long-term change in an attribute, value, or operational parameter of a system or equipment. The drift should be characterized, such as "diurnal frequency drift" and "output level drift." Drift is usually undesirable and unidirectional, but may be bidirectional, cyclic, or of such long-term ...

  7. Clock skew - Wikipedia

    en.wikipedia.org/wiki/Clock_skew

    If the clock arrival times at individual registers are viewed as variables to be adjusted in order to minimize the clock period while satisfying the setup and hold inequalities for all of the paths through the circuit, then the result is a Linear Programming problem. [3] In this linear program, zero clock skew is merely a feasible point - the ...

  8. Error analysis for the Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Error_analysis_for_the...

    This fraction is subtracted from 1 and multiplied by the pre-adjusted clock frequency of 10.23 MHz: (1 – 4.472 × 10 −10 ) × 10.23 = 10.22999999543 That is we need to slow the clocks down from 10.23 MHz to 10.22999999543 MHz in order to negate both time dilation effects.

  9. Clock - Wikipedia

    en.wikipedia.org/wiki/Clock

    The invention of the mechanical clock in the 13th century initiated a change in timekeeping methods from continuous processes, such as the motion of the gnomon's shadow on a sundial or the flow of liquid in a water clock, to periodic oscillatory processes, such as the swing of a pendulum or the vibration of a quartz crystal, [3] [79] which had ...
