Abstract
The analytical least-squares method has been generalized and extended for designing 16 types of two-dimensional FIR filters with quadrantall y symmetric or antisymmetric frequency responses. By means of a closed -form transformation matrix, this fast design method can determine the filter's coefficients very effectively without a recourse to an itera tive optimization technique or matrix inversion, Design examples are p resented to illustrate the simplicity and efficiency of the proposed m ethod.
