Statistical significance - Wikipedia, the free encyclopedia
In statistics, a result is called statistically significant if it is unlikely to have occurred by chance. The phrase ‘ test of significance ’, like so much in modern statistics, was coined by Rona...

In analog and digital communications, signal-to-noise ratio, often written S/N or SNR, is a measure of signal strength relative to background noise. ... If the incoming signal strength in microvolts is Vs, and the noise level, also in microvolts, is Vn, then the signal-to-noise ratio, S/N, in decibels is given by the formula...

In this section, we briefly summarise the properties of the aperture mass, i.e., its definition, its relation to the shear, and its signal-to-noise ratio. For more details, the reader is referred to S96 and SvWJK.

2.3.3. Signal-to-noise ratio ... In the following, the term S-statistics refers to the signal-to-noise ratio obtained from Eq. (22) using the filter function , which guarantees low noise in the signal-to-noise ratio map. The parameters , b, and c are determined once and are specified;

Signal-to-noise ratio, often abbreviated SNR or S/N, is an electrical engineering concept defined as the ratio of a signal power to the noise power corrupting the signal. In less technical terms, signal-to-noise ratio compares the level of a desired signal (such as music) to the ... Formula for the RMS noise voltage:;

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.
