Figure 6From: Assessment of pulse rate variability by the method of pulse frequency demodulationEffect of pulse height and baseline fluctuations. Simulated pulse wave signals were generated by a source interval function oscillating at 0.25 Hz (panel A) with stable pulse height and baseline (panel B), with fluctuating pulse height (panel C), and with fluctuating baseline (panel D). These fluctuations had no substantial influence (the estimation error, within ± 2 ms) on the results of the PFDM (panel E).Back to article page
