The analysis of modern digital pulse wave done. Among the several methods described in the article, the most promising in terms of real noise is now the method of discrete wavelet analysis. A multilevel decomposition of pulse waves using a discrete wavelet Daubechies family of different orders implemented. The technique of synthesizing a signal from the coefficients of the wavelet decomposition, which provides optimum correlation of coefficient between the original and reconstructed signal proposed. The most optimal Daubechies wavelets were the 5th and 7th orders. For these wavelets, this indicator is consistently high and depends little on the level of noise signal. |
