An Adaptive Filter Denoising Based on Wavelet Transform Applied in ECG Signal
Qian Xiao · Advanced materials research · 2012
Due to the fact that it is not easy to filter out the spectrum overlap noise between noisy signal and noise by using the traditional wavelet method, an adaptive filter model based on the wavelet transform is constructed in this paper. In the new filter, the adaptive filter is used to filter out noise secondary on the basis of wavelet denoising on the original noise signal. The experimental results show that the filter can effectively remove the noise. The new filter is applied to the denoising of the ECG signal, achieving a better filtering effect.
