Several new techniques for designing finite-duration impulse-response digital filters have become available in the past few years. The motivation behind three design techniques that have been proposed are reviewed here, and the resulting designs are compared with respect to filter characteristics, ease of design, and methods of realization. The design techniques to be discussed include window, frequency-sampling, and equiripple designs.
