Figure 7From: Real time reconstruction of quasiperiodic multi parameter physiological signalsEstimated signal qualities of a multi parameter signal. Signal quality estimates (SQE) of a multi parameter physiological signal. When all three signals are corruption-free, SQEs are approximately equal, and take an average of 0.33. When 20 dB AWGN is added to ABP and PPG signals (a), it results in an SQE 5× higher for ECG than others (average SQE for ECG is 0.8 compared to 0.16 of ABP) (b). At 10 dB AWGN the difference is more prominent (c).Back to article page
