| 摘 要： | 在临床医学中,采集到的心电信号仍然经常受到噪声的影响,由此采用滤波器来抑制这些干扰是十分必要的.通过对Levkov算法和Ahlstrom算法这2种算法的抑制工频干扰的性能进行研究,发现这2种方法都能够很好的保持原始波形的形状,并且计算量小,十分适合实时数字滤波的应用,证明其具有数字滑动平均,数字陷波以及自适应滤波方法所...

| Abstract: | In clinical medicine,ECG is jammed by noise,it is nessacery using filter to control the interence,this paper analyze the performances of the Levkov algorithm and Ahlstrom algorithm,and proved that they have many good qualities which the average filter,notch filter and self-adapting filter don't have in filtering power interference in ECG signals.At last,it draws the conclusion that both of the algorithms will have a good application prospect. |
