| Abstract | A design technique for a 2-dimensional finite impulse response filter based on a non-uniform frequency sampling approach is presented. Employing the zero-phase condition, the numbers of constrained equations are reduced and the filter coefficients of the resulting filter are all real numbers. In this method, a cost function can be constructed by a summation of the magnitude response deviation of all the sampling points. The Lagrange multiplier technique is utilized for the optimal solutions. |
