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 ...

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 ...

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” ...

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 ...

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 ...

Part 1 of this article series discussed the theoretical benefits of high-resolution audio’s large sample sizes and the degree to which the limitations of real-life equipment, recording studios, and ...

When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself.
