Clocks created from random events can probe ‘quantumness’ of universe

A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal. The researchers suggest that these ...

Windows feature that resets system clocks based on random data is wreaking havoc

WWV signals can be difficult to tune outside of certain hours and weather conditions. It's also fairly difficult to find WWV recievers that can easily plug into computers that aren't expensive bespoke ...

You can turn any random sequence of events into a clock

Any random sequence of events, such as the lapping of ocean waves on the shore, can become a clock – and physicists have now devised a mathematical procedure for making such an odd timepiece and for ...

Understand the effects of clock jitter and phase noise on sampled systems

As higher resolution data converters that can perform direct IF sampling come to market, system designers need help making performance-versus-cost trade-off decisions on low-jitter clock circuits.
