The Impact of Vial Cleanliness on Baseline Noise and Signal-to-Noise Ratio

The Impact of Vial Cleanliness on Baseline Noise and Signal-to-Noise Ratio

Signal to Noise Ratio – NIST Mar 6, 2017 · The sample signal to noise ratio (SNR) is defined as the ratio of the mean to the standard deviation: SNR = x¯ s. where s is the sample standard deviation and x¯ is the sample mean. This is the reciprocal of the coefficient of variation: cv = s x¯. That is, it shows the variability, as defined by the standard deviation, relative to the mean.
