Electrochemical Impedance Spectroscopy of Tap Water with the MFIA

on 06.01.2020 at 18:09 by Meng on Blog of Meng Li
Introduction Electrochemical impedance spectroscopy (EIS) is a popular non-destructive technique to characterize the physicochemical properties of materials, particularly at the solid-liquid (or electrode-electrolyte) interface. Despite the complexity of the measured data, EIS can be used to study many electrochemical devices […]

如何设置锁相放大器的低通滤波器

on 10.12.2019 at 06:10 by Fei on Blog of Fei
低通滤波器是锁相放大器的重要组成之一,决定了测量的性能。如何设置低通滤波器?低通滤波器的带宽(或者说时间常数)和阶数应该如何选择?在刚开始使用锁相放大器的时候,很多用户都有这样的疑问。对于简单的应用,带宽设置为解调频率的1/10到1/100,阶数设置为3或4,这就可以了。但是,为具体的应用找到最优的设置,可能要花很多时间。为了帮助用户快速地找到最优的设置,我们总结了几条经验跟大家分享。
