VibrationFrequencyWeighting (FPScript)
Filters an acceleration signal with a band-limited weighting filter for analyzing whole-body and hand-transmitted vibrations.
Syntax
VibrationFrequencyWeighting(Signal, FrequencyWeighting)
The syntax of the VibrationFrequencyWeighting function consists of the following parts:
Part |
Description |
||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Signal |
The acceleration signal to be evaluated. Permitted data structures are signal. All numeric data types are permitted. For the X component additional restrictions do apply.The values must have a constant positive spacing. Void values are not permitted in this argument. For complex data types the absolute value is formed. If the argument is a list, then the function is executed for each element of the list and the result is also a list. |
||||||||||||||||||||
FrequencyWeighting |
Chooses the frequency weighting. The argument FrequencyWeighting can have the following values:
If the argument is a list, then the first element in the list is taken. If this is also a list, then the process is repeated. |
Remarks
The result has the same structure and unit as the argument Signal.
