I'm trying to use the BMA 456 for some simple vibration measurement.
Would be interesting to know:
1) Does the BMA 456 has an anti-aliasing filter? As i read the datasheet, there is only an averaging filter.
2) Where does the 3dB Cutoff frequency come from? is this a filter function of the sensor, or is this due to mechanical damping?
Thank you very much for your help.
What is the vibration amplitude and frequency for your application?
