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 ...

Electrical noise, like taxes, is always with us. Most of the time noise is small and we can ignore it, but there are some measurement circumstances where noise must be dealt with. What can be done to ...

RF-to-baseband front ends consisting of a low-noise amplifier (LNA) cascaded with a mixer downconverting RF signals to baseband have become the epitome of RF devices tested in high-volume ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

Landsat 9 enhances Earth observation with 14-bit radiometric resolution, improved signal-to-noise ratio, and polar night ...

With today's applications requiring lower and lower noise-figure amplifiers, noise-source uncertainty becomes a bigger and bigger concern. Microwave modeling software ...

The ratio of interference in a circuit or line to the noise. A signal-to-noise ratio (SNR) deals with noise that comes from the inherent qualities of the electronic components or the atmosphere and is ...

The correlation function is a useful signal-analysis tool that engineers often overlook. Its formidable equation, which you have probably not thought about since your undergraduate signals and systems ...
