ADXL356 - VRE Effects


  I have a question about VRE in the ADXL356.

  What happens when there is a high-amplitude (close to 41g) high-frequency vibration at the same time as a low-amplitude low-frequency vibration, and we filter out the high-frequency signal using an analog LPF at the MEMS output? Will the VRE produced by the high-amplitude vibration affect the low-amplitude signal, even though the high-amplitude signal has been removed by filtering?

  I am concerned that, in this scenario, the low-amplitude signal could experience a VRE that is much higher than what it generates on its own.

  Thank you,
