ECG is the graphical recording of the electrical activity of the heart and this biological signal used for clinical diagnosis. The ECG signal is very sensitive in nature, and even if small noise mixed with original signal the various characteristics of the signal changes. The frequency components of a human°«s ECG signal fall into the range of 0.05 Hz to 100 Hz and as far as the noise are concerned. Hence filtering remains an important issue, as data corrupted with noise must either filter or discarded. This paper discusses overview of different filtering techniques used in ECG signal in recent research work.
