Statistics of the mean value and the standard deviation of fECG SNRs for different channels. For vertical axis of fECG SNR, the boxes stand for mean and the error bars stand for standard deviation. Five asterisk marks mean that the corresponding fECG SNRs are much higher than the other channels. H =1 indicates the significant difference between two adjacent channels at the 5% level in the two-sample T-test, while H =0 indicates no significant difference.
