摘要：

Digital or electronic displays of biosignals like electrocardiograms (ECGs) require noise reduction for accurate representation. In this paper noise reduction of normal ECG has been done using two types of filtering. The first type is band pass filtering of ECG, the filter taken from Pan Tompkins' algorithm of QRS detection, and the second type is Savitzky-Golay filtering of ECG. The band pass filter consists of a low pass filter with subsequent high pass filter. Then signal to noise ratio (SNR) has been calculated for the two types, after filtering to compare which method is better for ECG filtering. (C) 2011 Published by Elsevier Ltd.
