Improving the quality of filtering ecg signals due to the use of Wiener and Chebyshev filters
Ключові слова:
ECG signal, signal processing, noise, filteringАнотація
The paper investigates the causes of noise in electrocardiograms (ECG) and disadvantages of high-pass and low-pass filters by the example of a portable electrocardiograph. The use of Wiener and Chebyshev filters in an electrocardiograph is proposed. It is shown that the quality of ECG signal filtering with the use of Chebyshev and Wiener filters increased about 2 times as compared with high- and low-pass filters.
