Note 36. Designing FIR Filters: Kaiser Window Method
The Kaiser window is the window most often used in the windowing technique for designing linear-phase FIR filters that is described in Note 35. In order to exploit the adjustability of the Kaiser window most effectively, the filter design techniques presented in Note 35 must be modified, as shown for the lowpass case in Recipe 36.1. Comparing Recipe 35.1 and Recipe 36.1 reveals that Recipe 36.1 can be made generic with respect to band configuration if changes are made to steps 2, 8, and 9 to obtain the result shown in Recipe 36.2.
