An Efficient Teager Energy Operator-Based Automated QRS Complex Detection

Figure 7

Signal processing steps of the proposed R-peak detector using case 16272 with Gaussian white noise. (a) Low-pass filter; (b) the Teager energy; (c) moving average for eliminated spikes and BD stage; (d) detection of R peak. FP is false-positive prediction when the noise is detected. The Y-axis represents amplitude, and X-axis represents the samples.
