Windowing Function

Windowing Function

Default value is "None". You can select from "Hamming", "Bartlett", Harris-Blackman", "Blackman", "Hanning", "Parzen" and "Welch".

"Windowing" or apodization is the process of applying various weighting curves (generally named for their originators) to the data sample prior to spectrum analysis. Windowing reduces spectral leakage by suppressing sidelobes, but the process can also decrease overall resolution. Use of the correct Windowing Function can often aid in exposing low-amplitude cycles that are present in the data. There is no hard-and-fast rule for their application and you should experiment with the various windowing functions on a case by case basis. For general use of the cycleAnalyzer and cycleProjector indicators, though, we recommend that you leave this parameter set to its default value of "None".
