Estimation of accuracy ECG signal processing by cascade wide-band notch filtering method

This paper presents ECG signal processing results by cascade the wide-band notch filtering method. It is proposed to use Newton polynomials as an approximating polynomial of a wide-band notch filter. To eliminate the low-amplitude damped oscillations generated by the notch filters, the results forward-backward implementation cascade of Newton notch filters is presented. The forward-backward implementation cascade notch filters are demonstrated and based on the analysis of quantitative indicators the accuracy of ECG signal filtering is estimated.
