Scientists have taken a major step toward the ambitious global goal of “redefining the second” by the end of this decade. A ...

Rohde & Schwarz will present its new FSWX signal and spectrum analyzer for the first time to the public at the IEEE MTT-S ...

In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating ...

Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn't lose or gain a ...

Researchers from the University of Rochester and University of California, Santa Barbara, engineered a laser device smaller ...

The instrument provides information ... In a first step of the construction of material for the measurement of mental representations of terms on frequency and intensity a pool of terms commonly ...

Radio-frequency (RF) test-and-measurement instruments such as high-bandwidth oscilloscopes and RF digitizers use RF sampling analog-to-digital converters (ADCs) that simultaneously digitize ...

The VASI (Venus Atmospheric Structure Investigation) instrument aboard NASA’s ... measures changes in speed and direction by measuring the frequency shift of a radio signal from a transmitter ...

Record the frequency in Hertz. Hertz is a measure of how often something happens in one second. To calculate in Hertz, divide the number of waves you've counted by the time in seconds. Repeat this ...

Participants were able to reliably distinguish four frequency and intensity terms at both measuring times. Overall congruency between patients was larger for intensity terms in comparison to ...
