Validation of New and Existing Decision Rules for the Estimation of Beat-to-Beat Pulse Transit Time

Figure 4

Statistical results of the artificial data with various noise levels using different decision rules. From left to right: insets (a) to (d) show 4 artificial data with the addition of various intensity of simulated noise (i.e., SNR = , 15, and 35 dB, resp.). (e) to (h) show the distributions of standard deviations of all 11 methods.
