Wavelet transform is an effective tool for featureextraction, because this allows analysis of imagesat various levels of resolution. ConsideringtheDiscrete Wavelet Transform (DWT) basedwavelet, de-noising has been incorporated usingfour different thresholding techniques toremovethe three major sources of noisesfrom the acquired ECG signals namely,power line interference, baseline wandering,and high frequency noises. SEVEN waveletfunctions ("db1", "coif1","rbio1.1" , "dmey" ,"bior1.1" ,"haar" and "sym1") and fourdifferent thresholding levels (at 0.0056, 0.0156,0.0256 and 0.0356 levels) were utilised to denoise the ECG signals. This paper describestheway toprocesstheECGsignals(makethemnoisefree).
