[MEMS Studio] HPF feature bug

tomny · ‎2026-01-22

Hi,

I've tried to use high-pass filter in MLC in MEMS Studio, but the results are incorrect for first windows in each data file. I found that result is different from the one from Unico, but probably because Unico just drops first 2 windows from each file (which is an error itself).

Signal is a quite constant noise (sample data and project is attached).

These are F2_MEAN_ACC_Z_FILTER_1 & F3_MEAN_ACC_V_FILTER_2 from MEMS Studio and Unico.

Decision tree generated based on these filters makes no sense.

Values of these features read from FIFO looks ok. Looks like a bug in the app.

Best regards

Tomasz
