We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation corresponding to the ...

Atomic clocks and frequency standards represent the pinnacle of precision timekeeping technology. By harnessing the natural oscillatory behaviour of atoms, these devices deliver unparalleled accuracy ...

Polish physicists have been aiming to build an optical atomic clock, an extremely precise device with an accuracy of one second in a few dozen billion years, since 2008. The last of the three key ...

Different computer components run at different frequencies. For this reason they require a base frequency to synchronize their operations. The motherboard provides this in the form of an external ...

Earlier in March we heard about a quirk of the interconnected continental European electricity grid which caused clocks to lose about six minutes so far this year. This was due to a slight dip in the ...

I used to be able to hear 3kHz easily but as my hair cells fade into the sunset that frequency now seems to be down 3 or 6 dB. As a consequence the high pitched "beep beep" sound on my portable alarm ...

When measuring ultra-low-jitterdevices and equipment,engineers must constantly askwhether the measurement valuesare from the DUT (device undertest) or from the test equipment.Engineers are also always ...
