Abstract
A transformation method to convert rectangular symmetric two dimensional (2D) lowpass FIR digital filters to circular symmetric filters is presented. Based on this method, new designs of circular symmetric low/high pass filters are obtained. These designs have explicit formulae for impulse response coefficients and are much simpler than the existing designs
