Issue Details

I am attempting to use the Digital Filter function of the Crash Analysis Toolkit (Analysis >> Crash Analysis Toolkit >> Digital Filter).

I get an error similar to the following when I try to apply the filter.

Error: Limit frequency (f = 124.65 Hz) must be less than half the sampling frequency (f = 17.10 Hz).

Solution

The Digital Filter function expects the Time channel to be in the unit seconds. If it is not in seconds, convert them to seconds, either by using the ... conversion utility from the View tab, or by using the Convert Channel to Unit Set function.
