SVT Human Vibration Weighting Filter (octave) VI

SVT Human Vibration Weighting Filter (octave) VI

Owning Palette: Octave Extended Measurements VIs

Requires: Sound and Vibration Toolkit

Applies the selected human vibration weighting to octave spectra. This VI weights each spectral bin according to the attenuation of the specified filter at the bin center frequency. You can use this VI in a loop to process multiple blocks. Wire data to the octave spectrum input to determine the polymorphic instance to use or manually select the instance.

SVT Human Vibration Weighting Filter (octave) (1 Ch)

	octave spectrum specifies the octave spectrum to perform the operation on, in band power versus nominal frequencies. nominal frequencies [Hz] specifies the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power specifies the band power in decibels associated with each 1/n octave band.
	weighting specifies the type of weighting to apply to the input octave spectrum. Use Linear if you do not need any weighting. 0 Linear (Default) 1 Wh: hand-arm 2 Wb: vertical whole-body 3 Wc: horizontal whole-body 4 Wd: horizontal whole-body 5 We: rotational whole-body 6 Wj: vertical head 7 Wk: vertical whole-body 8 Wm: whole-body in buildings 9 Wf: low-frequency whole-body
	octave info in specifies octave measurement information for each channel. Note  You must wire octave info in when performing extended measurements. Do not modify the octave info in values. If you want to view the information, you can right-click the octave info in wire and select Custom Probe»Octave Info from the shortcut menu.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	weighted octave spectrum returns the weighted octave spectrum. nominal frequencies [Hz] returns the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power returns the band power in decibels associated with each 1/n octave band.
	unit label returns the engineering units for the weighted octave spectrum.
	total band power returns the total band power, in decibels, for the weighted octave spectrum. The default is 0.00 dB.
	octave info out returns information about the octave spectrum. Note  You must wire octave info out when performing extended measurements. Do not modify the octave info out values. If you want to view the information, you can right-click the octave info out wire and select Custom Probe»Octave Info from the shortcut menu.
	error out contains error information. This output provides standard error out functionality.
