Electrocardiogram (ECG) demonstrates the electrical activity of heart muscles over a period of time. The ECG is one of the extensively used physiological parameters for examination and diagnosis of cardiac diseases. The non-stationary ECG signal often gets contaminated with different noises. Hence, it is required to denoise the signal to provide accurate information to physicians. In this paper, Savitzky-Golay filter and Discrete Wavelet Transform (DWT) are being used to denoise ECG signal and a comparison is provided between two methods. The filter and DWT are applied on MITBIH arrhythmia database to check the robustness of proposed methods. Two parameters, signal to noise ratio (SNR) and mean squared error (MSE) are used for performance comparison.
