*Low-Pass (Antialiasing) Filter corner frequency*

Type: ``bool``

Help
====

High g events often include acceleration content over a wide range
of frequencies. The ADC of the ADXL372 samples the input acceleration
at the user selected ODR.
In the absence of antialiasing filters, input signals whose frequency
is more than half the ODR alias or fold into the measurement bandwidth
can lead to inaccurate measurements.
