On signal-to-noise ratio estimation
Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010A new simple algorithm for estimating signal-to-noise ratio (SNR) for a signal consisting of one sinusoid in white Gaussian noise is proposed in this paper. Algorithm is based on autocorrelation and modified covariance methods for AR (Autoregressive) spectral estimation.

We argue that the standard definition of signal to noise ratio may be misleading when the signal or noise are nonstationary. We introduce a new measure that we call local signal to noise ratio (LSNR) which is well suited to take into account nonstationary situations.

Signal-to-noise ratios in smooth limiters
IEEE Transactions on Information Theory, 1959Signal-to-noise ratios associated with smooth band-pass limiting and subsequent narrow-band filtering of a periodic signal and random noise are computed. Observed changes in signal-to-noise ratios may be used to estimate detectability losses. The error function is used to represent the limiter characteristic at various degrees of limiting.

Signal to noise ratio of information in documentation
Proceedings of the 22nd annual international conference on Design of communication: The engineering of quality documentation, 2004The signal to noise ratio is a common concept in radio communications and electronic communication in general. For a radio, the static is the noise. Too much static and the storm report gets drowned out, or at least you must listen closely to understand the announcer.

The signal-to-noise ratio (SNR) can be defined anywhere in the signal chain from the target to the display. The signal is usually the differential signal between a target and its background but the term differential is rarely used. Likewise, the noise is an rms value and the term rms is rarely used.

Signal-to-noise ratio in Fourier spectroscopy
Applied Optics, 1977Calculations of the SNR obtainable with a Fourier transform spectrometer as well as that obtainable with a photometer or scanning device are presented. It is shown that the SNR obtained with a Fourier spectrometer is (N/8)(1/2) greater than that obtained with a scanning device (where N is the desired number of spectral elements scanned).

Contrast and Signal-to-Noise Ratio
1996In an MR image, information is contained in the variation across the image of one single parameter: the grey level, which is a proportional to the signal level at that position. This parameter, called contrast, is the result of three properties of the imaged tissue: the proton density, p; the spin-lattice relaxation time, T 1; and the spin-spin ...
