Abstract/OtherAbstract:
Measured PPG signals are often contaminated with different noises and artifacts. For clinical diagnostics, it is important to have accurate signals. Removing noises and motion artifacts from PPG signal has been actual also in previous studies. In this study, we are proposing new adaptive impulse correlated filter (AICF) improvement for plethysmographic signals. It uses ECG signal to create reference with unit impulses. All signals, which do not correlate with reference signal, will be filtered out. To show, how the filter acts with artifacts with low SNR, the experiment was conducted.
