Windowing and Leakage

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 usefulĀ  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.

You will need Adobe Acrobat Reader to view any pdf files. It can be download for free from the Adobe website.
