Unformatted text preview: too high. You would like to keep your filter as short as possible to keep computations down. What should you do? a) Increase filter length N . b) Change your window choice or change window parameter (e.g. ± in a Kaiser-Bessel window) since your window is not sufficiently tapered. c) Do both (a) and (b). d) Do neither (a) or (b) or else you will violate filter design specifications. Answer: (c), since you must use a more tapered window to reduce passband ripple level, but this will increase transition bandwidth. You can then reduce transition bandwidth by increasing N....
