Decomposition of multidimensional filters
A. Venetsanopoulos, B.G. Mertzios · IEEE Transactions on Circuits and Systems · 1983
A theorem is proposed for the exact expansion of a generalm-dimensional rational function in terms of order one, each one of which is a function of each of themvariables. This decomposition can be used for the implementation of a general, linear IIRm-dimensional filter, with great modularity and parellelism in its structure.
