Applying a smoothing window to a signal is windowing. You can use windowing to complete the following analysis operations:

Define the duration of the observation.
Reduce spectral leakage.
Separate a small amplitude signal from a larger amplitude signal with frequencies very close to each other.
Design FIR filter coefficients.

The Windows VIs provide a simple method of improving the spectral characteristics of a sampled signal.

Note You can use the Windows VIs only in the LabVIEW Full and Professional Development Systems.
