The Signal to Noise Ratio ( SNR ) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) of power and therefor...

The signal to noise ratio is the difference between the noise floor and the reference level. The reference level is determined by the person making the measurements. For amplifiers, the reference may be, full power, one volt, one watt into a given load or any number of other things.

Notes on signal to noise ratio ... In most common cameras the signal to noise ratio will be in the order of 55 dB, i.e. a ratio of 562 : 1. That is, the signal is five hundred and sixty two times greater than the noise signal. At this ratio the noise will be unnoticeable.

A good measure of detectability of a flaw is its signal-to-noise ratio (S/N). The signal-to-noise ratio is a measure of how the signal from the defect compares to other background reflections (categorized as "noise").

Signal-to-noise-ratio (SNR) thresholds for microarray data analysis were experimentally determined with an oligonucleotide array that contained perfect-match (PM) and mismatch (MM) probes based upon four genes from Shewanella oneidensis MR-1. A new SNR calculation, called the signal-to-both-standard-deviations ratio...

Calculating signal to noise ratio (SNR) ; ... One more thing that is worth calculating before proceeding to group analysis is an estimate of the signal to noise ratio (SNR). To estimate the SNR, we need to use both the mean baseline contrast estimate, as well as the residual time series that was saved with the –errts...
