PHYSIOLOGICAL SIGNAL MEASURING SYSTEM AND METHOD THEREOF

Abstract

The physiological signal measuring method includes the following steps: obtaining a user physiological signal; separating the user physiological signal into multiple first packets according to a first box number; performing a sifting process respectively on the first packets by Empirical Mode Decomposition (EMD) to obtain multiple temporal intrinsic mode functions (temporal IMFs) respectively corresponding to the first packets; calculating multiple average envelope curves according to multiple upper envelope curves and multiple lower envelope curves respectively corresponding to the temporal IMFs; averaging the average envelope curves to generate a semi-IMF; calculating at least one correlation coefficient according to the semi-IMF and at least another semi-IMF; when the at least one correlation coefficient is larger than a correlation coefficient threshold, determining at least one signal section corresponding to the at least one correlation coefficient as at least one main component section of the user physiological signal.
