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 ...

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” ...

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 ...

This article addresses some basic noise principles and how to apply them to each analog-to-digital converter input node to minimize any noise convolving onto the output spectrum. Defining noise ...

Introduced as the industry's first sample rate converter with a signal-to-noise ratio (SNR) in excess of 130 dB, the AD1896 is also claimed to be the first such device to support the 192-kHz ...

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 ...
