Owning Palette: S&V Express Measurements Express VIs

Installed With: Sound and Vibration Measurement Suite. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Processing Express VIs to filter, scale, resample, and average signals; apply windowing and perform arithmetic operations; and, interactively align two signals.

The VIs on this palette can return ranges of LabVIEW error codes or specific sound and vibration error codes.

Palette Object	Description
Arithmetic (Frequency Domain)	Performs arithmetic operations on two signals. The available operations change depending on the type of the input signals you select.
Arithmetic (Time Domain)	Performs arithmetic operations on two signals. The available operations change depending on the type of the input signals you select.
Filter	Filters a time signal using an infinite impulse response (IIR) or finite impulse response (FIR) filter. Use this step to remove or attenuate unwanted frequencies from a signal using various standard filter types and topologies.
Formula	Performs math operations on up to four input variables. By default, Formula processes only one variable, but you can place checkmarks in the Enable checkboxes to enable more variables. Enter a formula in the Formula field using the variable names you specify in the Alias fields to represent the Input variable values.
Interactive Alignment	Aligns two plots so you can compare them. You can align the Test signal in signal with the Ref. signal in signal manually by dragging and/or expanding the Test plot on the graph or by using algorithms to automatically align steps, pulses, or periodic parameters.
Scaling and Conversion (Frequency Domain)	Performs gain and offset scaling on a time signal, gain scaling on a frequency-domain magnitude signal, or time-delay correction on a frequency-domain phase signal.
Scaling and Conversion (Time Domain)	Performs gain and offset scaling on a time signal, gain scaling on a frequency-domain magnitude signal, or time-delay correction on a frequency-domain phase signal.
Subset and Resample (Frequency Domain)	Extracts a subset of an input signal using the Start frequency and Subset length you specify or resamples an input signal using the frequency interval (df) you specify. If you specify a larger df, Subset and Resample downsamples the signal. If you specify a smaller df, Subset and Resample upsamples the signal.
Subset and Resample (Time Domain)	Extracts a subset of an input signal using the Start position and Subset length you specify or resamples an input signal using the time interval (dt) you specify. If you specify a larger dt, Subset and Resample downsamples the signal. If you specify a smaller dt, Subset and Resample upsamples the signal.
Time Averaging	Performs time averaging on a time signal or scalar input.
Window	Applies the window you select to the time-domain signal.
