Abstract
In a physiological signals processing system including (a) a A/D conversion means for converting physiological signals into digital signals and (b) a data compression means for reducing the number of data points sampled from said digital signals, the improvement which comprises: said data compression means being provided with a first sampling means for sampling a pair of combined peak points from said digital signals by applying the second order differential conversion to said digital signals, and a second sampling means for sampling level points by the level detection of said digital signals in the portion where adjacent peak points are not combined.
