Algorithm for stability test of multidimensional filters
N.K. Bose, P. Kamat · IEEE Transactions on Acoustics Speech and Signal Processing · 1974
An algorithm with a view towards computer implementation is given for stability test of filters of arbitrary dimension and complexity. The algorithm is based on the generation of a number of multivariable polynomials, reduction of each of these into several single variable polynomials by a finite number of rational operations, and a scheme of repeated single variable polynomial factorizations and back substitutions.
