Noise is the real enemy of data communications. Whenever electrons travel over a wire or radiate through space, they generate some electromagnetic noise. Therefore, whenever a data signal is sent ...

In my initial column last month, I talked about why I prefer charge-coupled device (CCD) cameras over hand-held digital ones. This month, I continue my discussion of CCD imaging by examining something ...

The term peak signal-to-noise ratio (PSNR) is an expression for the ratio between the maximum possible value (power) of a signal and the power of distorting noise that affects the quality of its ...

There is an art to making good measurements. In the ideal case, you want a really sensitive measuring device so that you can measure the smallest of changes to the signal you are interested in. But ...

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 ...

This article will review flow cytometry to help readers understand the challenges faced when increasing flow cytometer SNR (signal-to-noise ratio). Quick review: What is flow cytometry? Flow cytometry ...

Music labels and equipment suppliers hope that high-resolution-audio formats, such as DVD-Audio and SACD (Super Audio CD), will be the latest in a string of mostly successful upgrade “pitches” ...

While some companies are just beginning to wrap their heads around 5G and what it means for business, Bloomberg has been actively planning for the coming data deluge and using it as a driver to invest ...

The ratio of the power or volume (amplitude) of a signal to the amount of disturbance (the noise) mixed in with it. Measured in decibels, signal-to-noise ratio (SNR, S/N) measures the clarity of the ...
