I am attempting to use the LPF2 chain on the LSM6 accelerometers. The cut-off frequency is described as something like ODR_XL/100. I assume that means if you are running at 12.5 Hz the cutoff frequency is then .125 Hz. I am assuming that this is the 3 dB cutoff of the filter? I am still getting mechanical noise to make its way into the accelerometer response, so I am wondering what the actual design of the filter is. Is it just a single pole filter? Basically just a moving average of a 100 samples. Or is it a multi pole filter? and if so how many poles?
Thanks!

Hi @lasersocks , ya, probably the LPF2 is a single pole filter (-3dB the cutoff), since it is only defined by this frequency. But I let ST to validate this hypothesis.

Hi @TSand.1 , @lasersocks ,
that's correct.
