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 ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

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 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 ...
