| signal-to-noise ratio |
The ratio of power in a signal to the noise power in the channel. This term is usually applied to lower frequency signals, such as voice waveforms.

| signal-to-noise ratio |
(SNR or S/N ratio) - used to describe the relative contributions to a detected signal of the true signal and random superimposed signals ('noise'). One common method to improve (increase) the S/N ratio is to average several measurements of the signal in the knowledge that random contributions will tend to cancel out. ...

| signature |
Set of statistics that describe and define a training sample or cluster. It is used in multispectral classification. See also spectral response pattern and spectral signature.

| signal-to-noise ratio |
The ratio of the level of the information-bearing signal power to the level of the noise power. For MODIS, the ratio between (1) typical cloud free scene brightness with solar zenith angle Z=70 deg, and (2) all sensor and processing noise contributions. S/N specifications for various scenes (eg, land, clouds, oceans, ice) are only applicable in the filter bands associated with those scenes. Source: EPO.
