Abstract: In the design of a digital 2-D FIR filter, the frequency response is often optimised to satisfy a given set of specifications on a dense grid of frequency points. The accuracy of a filter design improves when there are more grid points, but this is at the expense of higher computational resources. The authors present the relationship between the accuracy and the frequency grid density in 2-D filter designs. A new formula for determining the frequency grid spacing is also proposed.
