"The Electrocardiogram (ECG) signal, which is a record of the electrical activity of the heart, can be\r\ntreated as a combination of a free-noise signal and noises. The primary source of interference in the ECG\r\nrecording during exercise is broadband myopotentials (EMG), contained in a full frequency band.\r\nBecause the frequency ranges of both signals (ECG and EMG) overlap, band-stop filters distort the ECG\r\nsignal, especially of QRS complexes. An alternative method of removing interference may be using\r\nAdaptive Wavelet Wiener Filter (AWWF) with noise-free signal estimation. As a result of a\r\nstraightforward wavelet transform, it is possible to extract noise with some components of the QRS\r\ncomplex in the highest frequency bands. The central part of the QRS components is in the lower\r\nfrequency bands. The resulting signal can be filtered by matching the transform coefficients. Testing was\r\nperformed on muscle (EMG) artifact noised signals from the MIT-BIH Noise Stress Test Database at 360\r\nHz sampling frequency."^^ . "2019" . . . . . . . . . . . . . . "Van Manh"^^ .
