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.
