Abstract : Various approaches to the frequency-sampling design of two-dimensional FIR filters are analyzed. The IDFT approach requiring uniform sampling on a Cartesian grid is first described. A method which allows arbitrary placement of frequency samples but which does not satisfy the Haar condition is presented. Finally, a novel, computationally efficient method which allows nonuniform sampling and which always provides a unique design solution is presented. The new approach is compared with the other methods in terms of design flexibility, computational efficiency, and performance. Keywords include: Filters; Digital; Two-Dimensional; Finite impulse response(FIR); and Frequency-sampling.
