摘要

为在动态条件下进行快速阻抗谱分析，提出了降低信号处理算法和硬件解决方案复杂性的方法。最小的计算资源和低功耗是嵌入式系统应用的先决条件。开发了两种简单的技术——激励波形的合成和响应信号的处理。只实现了信号的低电平量化，并且首选它们的归一化电平为+1、-1和0。

Embedded Signal Processing in Impedance Spectroscopy

Methods for reducing the complexity of both - signal processing algorithms and hardware solutions - are proposed for performing the fast impedance spectroscopy in dynamic conditions. Minimal computational resources and low power consumption are the prerequisites for applications in embedded systems. Simple techniques for both - synthesizing of excitation waveforms and processing of response signals - are developed. Only a few-level quantization of signals is implemented and their normalized levels as +1, -1, and 0 are preferred.
