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 ...

A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...

In physics and engineering, the “signal-to-noise ratio” essentially compares the level of meaningful information, signal, to the level of undesired disturbance, noise. The greater your signal-to-noise ...

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” ...

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.

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 ...

Two years ago, a medical professional approached scientists at the University of Tabriz in Iran with an interesting problem: Patients were having headaches after pacemaker implants. Working together ...
