OBJECTIVE
The authors Lang and Zalka commented on our previous note (Louarroudi and Sanchez 2017 Physiol. Meas. 38 N73-80), indicating interpolation as a suitable method to estimate the instantaneous impedance of a time-varying impedance from stepped-sine excitations.
APPROACH
Here, we briefly delve into the underlying assumptions of the interpolation scheme.
MAIN RESULTS
We illustrate the approximation of the instantaneous impedance of a time-varying impedance from stepped-sine measurements conducting experiments on a phantom.
SIGNIFICANCE
We outline the technical challenges awaiting future research required to validate the accuracy of the instantaneous impedance approximation of a time-varying impedance using stepped-sine excitations.
目的
作者 Lang 和 Zalka 评论了我们之前的注释（Louarroudi 和 Sanchez，2017 年《生理学测量》38 卷 N73-80），指出内插法是一种从阶跃正弦激励中估计时变阻抗瞬时阻抗的合适方法。
方法
在此，我们简要探讨了内插方案的基本假设。
主要结果
我们通过在体模上进行实验，展示了从阶跃正弦测量中估算时变阻抗瞬时阻抗的方法。
意义
我们概述了未来研究所需的技术挑战，以验证使用阶跃正弦激励来估算时变阻抗的瞬时阻抗的准确性。
