On the signal-to-noise ratio wall

WebSignal-to-noise ratio is defined as the ratio of the power of a signal (meaningful information) and the power of background noise (unwanted signal): SNR = Psignal Pnoise. If the variance of the signal and noise are known, and the signal is zero: SNR = σ2 signal σ2 noise. If the signal and the noise are measured across the same impedance, then ... WebTo obtain a useful signal, we used the spectral approach to remove noise. The best signals were obtained at a distance of 10 mm (SNR median is 63). Good quality signals were also obtained at distances of 6 and 8 mm (SNR medians are 49 and 55, respectively). It was found that calculated BF is directly proportional to the source-detector separation.
