A signal-piloted linear phase filtering tactic for removing baseline wander and power-line interference from the electrocardiogram (ECG) signals is suggested. The system is capable of adjusting its parameters by following the incoming signal variations. It renders the processing of lesser samples by inferior order filters. The applicability is demonstrated by using the MIT-BIH ECG database. The precision of the approach is also studied regarding the signal-to-noise ratio (SNR). Results showed that the proposed method achieves a 2.18-fold compression gain and notable computational efficiency over conventional counterpart while securing an analogous output SNR. A comparison of the designed solution is made with the contemporary empirical mode decomposition with Kalman filtering and eigenvalue decomposition based tactics. Results show that the suggested method performs better in terms of output SNR for the studied cases.
本文提出了一种用于去除心电图(ECG)信号中基线漂移和电力线干扰的信号驱动线性相位滤波策略。该系统能够根据输入信号的变化来调整其参数。它通过低阶滤波器处理较少的样本。通过使用麻省理工学院-贝斯以色列女执事医疗中心(MIT-BIH)心电图数据库证明了该方法的适用性。还研究了该方法在信噪比(SNR)方面的精度。结果表明,与传统方法相比,该方法在保证类似输出信噪比的同时,实现了2.18倍的压缩增益和显著的计算效率。将设计的解决方案与基于卡尔曼滤波和特征值分解的当代经验模式分解方法进行了比较。结果表明,在所研究的案例中,该方法在输出信噪比方面表现更好。
