DADiSP / ISO 2631 1.6
ISO 2631 Frequency Weighting Module New
The ISO 2631 Module designs and processes data with ISO 2631
frequency weighting curves. Three principal frequency weightings
are described in the ISO 2631 Standard: Wk for the Z axis or
vertical direction, Wd for the X and Y axes, or horizontal
direction, and Wf for motion sickness.
Additional frequency weightings defined for the special cases of
seat-back measurements, rotational vibration and vibration under
the head.
The ISO 2631 Module supports all 8 of the defined ISO 2631 frequency
weighting curves, Wb, Wc, Wd, We, Wf, Wj, Wk and Wm weighting
filters. In addition, the the ISO 5341 Wh and British BS 6841 Wg frequency
weighting filters are included to provide a complete, standards
based frequency weighting solution.
Acceleration data is processed by the frequency weighting filter in
one step, where the filter is designed as per the selected
specification and the data is filtered in the time domain with a
high precision digital filter.
