Atomic gravimeters are used to accurately measure gravity by detecting the quantum interference patterns of freely falling atoms in a vacuum. However, these devices are typically bulky and complex, ...

Well-known biological processes rely on protein structural changes, such as neuron signal transmission and oxygen transport. The opening and closing of ion channels for signalling currents depends on ...

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 ...

Magnetic resonance imaging (MRI) is widely used in medicine to detect, diagnose and treat diseases such as cancer, while relying on experts' interpretation of images. Quantitative MRI, which obtains ...

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 ...

As photonics technology becomes increasingly sophisticated, optical measurements grow increasingly complex. To make reliable measurements, one must consider the characteristics and interactions of ...
