In considering communication link performance, signal-to-noise ratio (SNR) is an extremely important concept. It is the common way to quantify the quality of the signal at any point in the communication process. Ultimately, it is the SNR that determines whether or not adequate communication takes place, but as will be seen in later chapters its ...

Mixed‐bandwidth acquisitions: Signal‐to‐noise ratio and signal‐to‐noise efficiency
Journal of Magnetic Resonance Imaging, 2010AbstractPurposeTo 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 ...

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.

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.

Comparison of Signal-to-Noise Ratios
Analytical Chemistry, 1997The probability distribution (density) function for the experimental signal-to-noise ratio (SNR) defined as x/s, where x is the sample mean and s is the customary sample standard deviation, has been derived and found to be in excellent agreement with accurate Monte Carlo simulation results.

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.
