The parameters are described in the following table:
Integration Parameters
Description
A simple or double operation can be done. A first (simple integration)
or second order (double integration) filter is used following this
parameter.
This is the cut-off frequency for the filter used in the integration
process. We suggest using an Fcut(Hz) parameter that fits with the
sensor used. A typical accelerometer sensor has a flat frequency
response that starts at around 20 Hz.
This control allows selecting the group of channels for which the integration will be done.
This button launches the integration operation.
