HIgh pass filter cutoff setting in MMA8451Q Transient detction

Question asked by Pawan Das on Mar 9, 2017



    I am using MMA8451Q for Transient detection functionality by referring the Application Note 'AN4071 - High-Pass Filtered Data and Transient Detection Using the MMA8451, 2, 3Q'.


   In the App Note, they have mentioned about using High pass filter data for Transient detection functionality. But in section 7.1, Example Steps for Configuring Transient Detection, the steps required for setting the cutoff for High pass filter isn't included.


   As high pass filter is used for transient detection, could you please clarify the configuration steps required to set Filter cutoff; which is missing in the steps given in the document.


   Any help is greatly appreciated. Thanks in advance.
