I am trying to observe the acceleration caused due to a deterministic sudden impact with an ADXL375 device.
I notice that the peak acceleration being reported varies with the bandwidth setting. The value gos as high as 150g at a BW of 400Hz, and the same impact drops down to about 60g when sampled at 100 Hz.
Is this variation a result of the decimation being performed to down sample the acceleration signal to the desired (lower) bandwidth?
How can I tell what is the "correct" peak acceleration based on these readings?
The width of the acceleration spike at impact was measured to be of the order of 10 millisec.
