A novel method for nonuniform frequency-sampling design of 2-D FIR filters
W.J. Rozwod, Charles W. Therrien, Jeong Sik Lim · 2003
The authors present a novel frequency-sampling design method for two-dimensional FIR filters with nonuniformly spaced samples. By imposing some mild constraints on sample location in the 2-D frequency plane, the method always provides a unique design solution. Important characteristics of the method are design flexibility through use of nonuniform samples and computational efficiency.>
