摘要: A method, based on 2-D asymmetric half-plane lattice parameters, for the design of two dimensional (2-D) recursive digital filters is presented. The procedure calculates parameter factors from prescribed frequency characteristics. order controlled by an a priori error criterion, corresponding to minimum mean squared between successive stages. stability resulting filter determined at each stage computed reflection factors. capabilities proposed approach are demonstrated fan and circularly symmetric lowpass filter. computer time their seconds both filters.
