SVT Human Vibration Weighting Filter (Fixed Rates) VI
Owning Palette: Weighting and Filtering VIs
Requires: Sound and Vibration Toolkit
Applies the selected human vibration weighting to a scaled signal expressed in engineering units. This VI complies with ISO 8041:2005 (E), JIS B 7760:2004, and JISB 7761:2004 standards. Each instance of this VI maintains its own state; use the N Channel instance of this VI to process an array of channels. This VI operates on time-continuous data; it resets on a discontinuity. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.

scaled signal [EU] specifies the scaled signal expressed in the selected engineering units. To obtain a properly scaled signal, you can use the SVL Scale Voltage to EU VI or define a virtual channel in National Instruments Measurement & Automation Explorer (MAX).
| ||||||||||||||||||||
 |
weighting specifies the type of weighting to apply to the input time-domain signal. Use Linear if you do not need any weighting.
|
||||||||||||||||||||
 |
error in describes error conditions that occur before this node runs. This input provides standard error in functionality. | ||||||||||||||||||||
 |
reset filter specifies whether this VI resets the weighting filter. The default is FALSE. The first time you call this VI, the filter restarts automatically. | ||||||||||||||||||||
 |
weighted signal [EU] returns the weighted signal based on the signal and weighting input specifications.
| ||||||||||||||||||||
 |
error out contains error information. This output provides standard error out functionality. |
