Specific filters are used to weight the acceleration signal before calculating the <math>D_k</math>. These filter are different for the vertical and horizontal direction, and are defined for a sampling rate of 160 Sample/second. Therefore, we advise to [[NVGate Recorder|record]] the signal with a low [[NVGate_Front_End#Input_settings|sampling rate]] in NVGate.<br> | Specific filters are used to weight the acceleration signal before calculating the <math>D_k</math>.
