Kaiser window function
WebbLet’s start with windowed, truncated lowpass filters, then other kind of filters, like highpass, bandpass, and bandstop filters can also be achieved by several techniques. Any finite-length of the ideal lowpass impulse response may be considered as the product of the infinite-length lowpass impulse response and a window function W, WebbKaiser-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 …

The following values are particularly interesting: alpha ----- 0 Rectangular Window 5 Similar to Hamming window Webb0 is the zeroth-order modi ed Bessel function of the rst kind. Remarks: I When = 0, w K[n] = w r[n] (the Kaiser window becomes a rectangular window). I The 0 parameter allows for a tradeo between side lobe amplitude A SL and main lobe width ML.
