TSpectrum.MainlobeWidth Property

Defines the width of the main lobe. Each frequency component in the frequency spectrum should theoretically be infinitely thin.

Pascal
property MainlobeWidth: integer;

Because of spectral leakege (Gibbs phenomenon), each spectral component has certain width (in [Hz]). This width depends on the spectral window used. (Hanning, Hamming etc..) The derived classes can set this property to match up to the spectral window used when computing the frequency spectrum. This parameter is used by different statistical methods to improve the accuracy of the estimate. (THDN, SINAD, RMS...).
