AD5941 滤波器设置

Thread Summary

The user encountered reduced precision with the sin3 filter at frequencies below 10Hz in EIS testing. The final answer suggests using the sin2 filter for low frequencies and recommends checking the AD5940.H header file for configuration parameters. The official example for AD5940 EIS is available on the Analog Devices GitHub repository.

在测试中我发现使用的 是sin3,在高频精度尚可,但是在低于10Hz精度明显下降,所以在低频的时候我应该用sin2滤波器嘛,里面的参数应该如何设置呢?有没有官方例程对应讲解一下呢?
