Key result
Statistical weighted moving average filter extracts ECG baseline wander and preserves morphology better than traditional filters.
Why the study?
Does a statistical weighted moving average filter improve baseline wander removal and preserve morphological features in ECG signals compared to traditional filters?
Does a statistical weighted moving average filter improve baseline wander removal and preserve morphological features in ECG signals compared to traditional filters?
A novel statistical weighted moving average filter effectively removes baseline wander from ECG signals while preserving morphological features better than traditional methods.

Hu et al. (2011) studied Baseline wander in ECG signals. Statistical weighted moving average filter vs. Traditional moving average filter and wavelet package translation was evaluated on Extraction of baseline wander and preservation of morphological features. A statistical weighted moving average filter more effectively extracted baseline wander from ECG signals and preserved morphological features better than traditional filters and wavelet translation.
