Windows are a  tool commonly used in frequency domain signal processing to preserve the amplitude of a signal and/or minimize leakage.  In Dynamic Systems work, windows are useful  for determining the frequency content and amplitude of a signal when analyzing the signal in the frequency domain.  

 

A stand alone LabVIEW GUI is available. The LabVIEW GUI .zip file contains a document of suggested exercises to be performed with the GUI.
