A noise reduction algorithm in ECG signals using wavelet transform

2nd International Biomedical Engineering Days Conference -- MAY 20-22, 1998 -- ISTANBUL, TURKEYWOS: 000076010900008A noise reduction algorithm based on multiresolution orthogonal wavelet transform in ECG signals is discussed. The 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 from 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.Bogazici Univ, Inst Biomed Engn, IEEE, Engn Med & Biol So
