WebThe rectangular window s(n), has a very narrow mainlobe, but very high sidelobes. Usually, it is desired to decrease the sidelobe height at the expense of a wider mainlobe. Some windows provide a parameter that can be varied to control this trade-o (Kaiser window, Prolate spheroidal window, Dolph-Chebyshev window). I. Selesnick EL 713 Lecture ... WebKaiser-Bessel. This is a Kaiser-Bessel window with the parameter pi*alpha = 11.9. The maximum side-lobe level is around -89.09 dB. The normalized ENBW varies slightly with window length, but converges on 2.00126601155359 Hz-sec for large window lengths. This window is very similar to the Blackman-Harris window.
