Abstract :
In the paper, the authors propose a novel algorithm for synthesis of 2-D lossless FIR filter transfer function matrix. The synthesis based on 2-D embedding technique is used to obtain a FIR filter transfer function matrix which possess lossless properties. The matrix is composed of desired 2-D linear phase, quadrant symmetry transfer function and additional nonlinear phase transfer functions. A Newton algorithm was used to solve a system of equations describing 2-D lossless system.
