More Information
Summary:A method for measuring a physiological signal is provided. The method is applicable to optical physiological measurement with at least two types of light sources. The method includes a processing for adjusting amplitudes of signals of the at least two types of light sources to a predetermined ratio by adjusting intensities of the light sources, so as to increase a signal dynamic range as well as a signal-to-noise ratio.
