Normalized pulse volume for the each condition.

Here the derivation of the normalized pulse volume for the two photoplethysmogram systems for each of the two wavelengths is depicted. AC = alternating-current component, DC = direct-current component, FPPG = finger-photoplethysmogram.本内容展示了两种波长下，两套光电容积脉搏波（photoplethysmogram, PPG）系统的归一化脉搏容积推导过程。其中，AC为交流分量（alternating-current component），DC为直流分量（direct-current component），FPPG指代指端光电容积脉搏波（finger-photoplethysmogram）。
