*Low-Pass (Antialiasing) Filter corner frequency*

Type: ``bool``

    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.
