Abstract

A noise reduction algorithm based on the multiresolution orthogonal wavelet transform for ECG signals is discussed. Results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley and Daubechies for two different noise characteristics. The first one is artificially obtained line interference sinusoidal noise and the second one is uniformly distributed random noise or white noise. The results show that the former noise is completely eliminated front the signal by using both of the filter coefficients. However. The latter noise did not give the same performance as that of the former one
