Figure 6From: A hybrid approach to the simultaneous eliminating of power-line interference and associated ringing artifacts in electrocardiogramsHistograms and relevant statistical results of artificial data sets. From left to right: the four columns, (a)-(e), (f)-(j), (k)-(p) and (q)-(u), show results of data sets with f s of 250, 360, 500 and 1000 Hz, respectively. For each data set, from top to bottom: the first four rows show results of four groups, including groups ❶, ❷, ❸ and ➍, respectively. Four curves in each inset in the last row, which contains (e), (j), (p) and (u), correspond to four histograms in the same column and ordered by the legends, respectively.Back to article page
