Abstract

Wavelet transform is an effective tool for feature
extraction, because this allows analysis of images
at various levels of resolution. Consideringthe
Discrete Wavelet Transform (DWT) based
wavelet, de-noising has been incorporated using
four different thresholding techniques to
removethe three major sources of noises
from the acquired ECG signals namely,
power line interference, baseline wandering,
and high frequency noises. SEVEN wavelet
functions ("db1", "coif1","rbio1.1" , "dmey" ,
"bior1.1" ,"haar" and "sym1") and four
different thresholding levels (at 0.0056, 0.0156,
0.0256 and 0.0356 levels) were utilised to denoise the ECG signals. This paper describes
theway toprocesstheECGsignals(makethemnoisefree).
