Abstract :
To develop a noninvasive circulatory parameter measuring method by analyzing waveforms of the digital plethysmograms (DPTG), we measured DPTG of subjects of widely ranging age and performed Fourier analysis. DPTG waveforms were well approximated by the sum of the first ten harmonics and well characterized by their frequency spectra
