Abstract: Objective To study the application of dual-frequency impedance pneumography and adaptive filter for reducing motion artifacts in respiration monitoring.

目的对应用双频率阻抗测试和自适应处理技术相结合的方法消除呼吸阻抗测量中的运动干扰问题进行一些探索性的研究。

Numerical simulation studies indicate that the adaptive filter is a powerful noise suppresser for correlated interferences, especially for those with amplitude changing and time delay.

数值模拟结果表明该滤波器对于相关噪声，尤其是有幅值变化和时间延迟的情况，有很强的抑制效果。
