In no field of science is the gulf between appreciation and importance as wide as it is for metrology. It’s not about the weather. Metrology is the science of measuring. It has a longer history than ...

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

One of the best things about digital oscilloscopes is that they can measure the acquired waveforms using a wide range of helpful measurement parameters. Most current oscilloscopes include about twenty ...

ONE of the reasons for the success of the scientific method is the rigorous control of the conditions of measurement. The effect of varying one parameter is examined while the other conditions are ...

A new set of precision distance measurements made with an international collection of radio telescopes have greatly increased the likelihood that theorists need to revise the “standard model” that ...

Improvements to the SI are helping to evolve the science of accuracy and measurement. Democratization of the SI creates a traceability calibration chain accessible to anyone, anywhere. Digitization of ...

The author is technical publications manager and a senior technical writer at Audio Precision in Beaverton, Ore. When reduced to its basics, the process of audio test and measurement is concerned with ...
