Abstract:
Ten non-recursive filters were investigated for power-line interference extraction from appropriate ECG segments. This extraction is a part of the subtraction procedure for interference cancellation, which is known to not affect the own signal frequency components overlapped by the interference band. The filters were tested in equal conditions defined by a set of real ECG signals mixed with 50 Hz synthesized interference. The impulse, the frequency and the phase responses of the filters were analysed. The filter efficiency is evaluated on the base of several errors, which were calculated as differences between the ECG signals before and after applying the subtraction procedure.
