The signal-to-noise ratio (SNR) required for the estimation of foliar biochemical concentrations
International Journal of Remote Sensing, 1996Abstract This paper compares estimates of the signal-to-noise ratio(SNR) required by imaging spectrometers for the estimation of foliar biochemical concentrations and the SNR currently achieved by ...

Signal-To-Noise Ratio (SNR) For Reliable Data Recording
SPIE Proceedings, 1987Due to the nonlinear nature of the thermal optical recording process and the inherent difficulty in tracking and maintaining focus of a submicron-sized light spot, peak-shift values of 40 to 50% are likely to occur during the use of an optical data storage system.

The measurement of the signal-to-noise ratio (SNR) in continuous speech
Speech Communication, 1987Abstract In voiced speech segments, natural noise is the sum of modulation noise due to the irregularly vibratory patterns of the vocal folds, and additive noise due to the air stream in a glottal chink. The noise content can be evaluated by the signal-to-noise ratio (SNR).

On the signal‐to‐noise ratio benefit of spiral acquisition in diffusion MRI
Magnetic Resonance in Medicine, 2020Spiral readouts combine several favorable properties that promise superior net sensitivity for diffusion imaging. The purpose of this study is to verify the signal‐to‐noise ratio (SNR) benefit of spiral acquisition in comparison with current echo‐planar ...

Research on signal-to-noise ratio (SNR) affect physiological parameters in tumor
2010 3rd International Conference on Biomedical Engineering and Informatics, 2010Deconvolution method has been used to estimate physiological (functional) parameters, such as blood flow (F), blood volume (V), mean transit time (MTT), and capillary permeability surface area product (PS), but it is very sensitive to the effect of noise.

Improving the Signal‐to‐Noise Ratio of Seismological Datasets by Unsupervised Machine Learning
Seismological Research Letters, 2019Seismic waves that are recorded by near-surface sensors are usually disturbed by strong noise. Hence, the recorded seismic data are sometimes of poor quality; this phenomenon can be characterized as a low signal-to-noise ratio (SNR).

Evaluation of signal to noise ratio (SNR) of log periodic dipole antenna (LPDA)
2013 IEEE Business Engineering and Industrial Applications Colloquium (BEIAC), 2013Logarithmic periodic dipole antenna (LPDA) was constructed for monitoring Sun in the range of (45 -870) MHz to precisely match the solar monitoring requirements. In our work, we choose rod aluminium's type as a conductor with nineteenth (19) elements of different sizes.

Series analysis of Signal to Noise Ratio (SNR) in active mode-locked lasers
2007 IFIP International Conference on Wireless and Optical Communications Networks, 2007Analysis of active mode-locked laser under the influence of asynchronous spontaneous emission (ASE) noise by using series approach is presented in this paper. Transient evolution and steady state of the mode-locked pulse are studied in details by the use of mathematical series approximating the generated pulse.
