Filter bank-based processing of the stress ECG
The algorithm presented is based on subband processing of the electrocardiogram (EGG), using Filter Banks (FB), and removes noise from stress-type ECGs. For Gaussian noise the FB-based method improves the signal-to-noise ratio (SNR), significantly better than the Mean and Median averaging methods. For muscle noise the FB-based method improves the SNR comparatively better than the Mean and Median averaging methods. The FB-based algorithm offers a way to process specific time periods in the heart beat cycle and remove noise in specific frequency bands.
