Title: Band-stop Filter Tuning for Power-line Interference Rejection in ECG Signals
Keywords: Digital filtering, ECG signal, Filter tuning, Power-line interference rejection

Abstract: The paper proposes a procedure for digital band-stop filter tuning on purpose to extract power-line interferences from ECG signals. The procedure consists of three stages: i) - an inaccurate auxiliary bandpass filter is applied to the signal, which inaccurately extracts the power-line interference; ii) - with an additional filter the deviation of the power-line frequency from its nominal value is determined; iii) - parameters of a precise band-stop filter are corrected from the determined interference frequency deviation. To work with an ECG signal at a high sampling rate, an appropriate reduction of the digital filters used is proposed
