USING OF FIR AND IIR FILTERS FOR NOISE REMOVAL FROM ECG SIGNAL: A PERFORMANCE ANALYSIS

Electrocardiogram (ECG) is a widely used routine and important cardiac diagnostic tool where in electrical signals are measured and recorded to know the functional status of heart. Quiet often, various artifacts corrupt the original ECG signal and reduces it quality. Therefore, there is a need to remove such artifacts from the original signal and improve its quality for better interpretation. ECG signals are very low frequency signals of about 0.5Hz-100Hz and digital filters are used as efficient means for noise removal of such low frequency signals. This paper presents the comparative analysis of FIR and IIR filters and their performances to remove Baseline noises from the ECG signal for proper understanding and display of the ECG signal.
