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

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 ...

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 ...

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 ...

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 ...
