Reduction of Power Line Interference by Using Adaptive Filtering Techniques in Electrocardiogram
نویسنده
چکیده
Electrocardiogram (ECG) signal is affected by many noise interferences. Out of all the noise effects the power line interference is the predominant one. In this paper the implementation of the adaptive algorithm techniques for reduction in this power line interference is shown and a comparison of these techniques is performed. The adaptive filters used have shown a good improvement in the SNR (Signal– to – Noise Ratio). The LMS (Least mean square), NLMS (Normalized LMS), and SLMS (Sign LMS) algorithms are discussed and compared.
