Enhancement of signal-to-noise ratio

Journal of Statistical Physics, 1997
It is shown that the ratio of signal-to-noise ratio at the output to that at the input can be made larger than unity when a nonlinear system is subjected to a weak periodic perturbation and a harmonic noise. This theoretical result is in conformity with the experimental observation published recently by R. Liet al.

Signal-to-Noise Ratio

2009
To quantify the instrument's performance, the spectral signal-to-noise ratio (SNR) is used as the main measure throughout this book. The term has been used somewhat inconsistently; in some cases, it is used to quantify spectral repeatability, and in others, it is used to quantify spectral accuracy.

Mixed‐bandwidth acquisitions: Signal‐to‐noise ratio and signal‐to‐noise efficiency

Journal of Magnetic Resonance Imaging, 2010
AbstractPurposeTo evaluate signal‐to‐noise ratio (SNR) and SNR efficiency in mixed‐bandwidth acquisition (MBA). SNR efficiency describes the achievable SNR per unit time and is a basic aspect in clinical applications to optimize work flow.Materials and MethodsCorresponding simulations were performed and predictions of the theory verified in phantom ...

Signal-to-Noise Ratio

2017
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.

A Signal-to-Noise Ratio Enhancer

2011 IEEE Sensors Applications Symposium, 2011
Many radio applications require a Signal-to-Noise Ratio (SNR) Enhancer to combat the radio channel impairments. In this paper, we are particularly interested in combating the radio channel impairments resulted from long-term and short-term channel variations. The SNR Enhancer pre-conditions the received signal strength (RSS) of the signal such that the

A signal-to-noise ratio model for the speech-reception threshold of the hearing impaired.

Journal of Speech and Hearing Research, 1986
This paper reviews the results of a series of investigations inspired by a model of the speech-reception threshold (SRT) of hearing-impaired listeners. The model contains two parameters accounting for the SRT of normal-hearing listeners (SRT in quiet and

Signal-to-noise ratio advantage of binaural hearing aids and directional microphones under different levels of reverberation.

Journal of Speech and Hearing Disorders, 1984
The signal-to-noise ratio necessary for a constant performance level was determined for normally hearing and hearing-impaired subjects under three levels of reverberation (0.3, 0.6, and 1.2 s) with monaural and binaural hearing aids having directional ...

The signal-to-noise ratio of human divers

OCEANS'10 IEEE SYDNEY, 2010
A challenging problem in underwater acoustics is the detection and tracking of human divers. In order to assess the suitability of different tracking methods on this problem, an evaluation of the signal-to-noise ratio (SNR) is required.
