Kaiser Window

With the filter length and Kaiser window $\beta=8$ as given above, we may compute the Kaiser window itself in matlab via

  w = kaiser(M,beta)'; % Kaiser window in "linear phase form"

The spectrum of this window (zero-padded by more than a factor of 8) is shown in Fig.4.9 (full magnitude spectrum) and Fig.4.10 (zoom-in on the main lobe).
