- choice: Low-Pass (Antialiasing) Filter corner frequency
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.
