Research ArticleOpen accessIn the keywordsA Comparative Study of Stability Testing Approaches of Two-Dimensional Recursive Digital FiltersK. R. Santhi, M. Ponnavaikko, N. GangatharanThere are many problems in science and engineering whose solution is applied in the design of Multi-Dimensional (MD) digital filters. Digital filtering finds an important position in the field of digital signal and image processing. Recently there had been a great deal of interest in the design and stability analysis of Two-Dimensional (2-D) recursive digital filters. The design techniques for … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,867 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Note on the Bivariate Lagrange Interpolation PolynomialsDan BărbosuThe focus of the research is to obtain reccurence formulas for the bivariate Lagrange interpolation polynomials, similar to the reccurence formulas verified by the univariate Lagrange interpolation polynomials. …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,697 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Overview of Modified Shanks’ Conjecture and Comments on its ValidityN. Gangatharan, T.C. ChuahThis study reports the validity of the modified Shanks’ conjecture on the planar least squares inverse (PLSI) method of stabilizing two-dimensional (2-D) recursive digital filters. A theoretical procedure proposed based on the Lagrange multiplier method of mathematical optimization. The results indicate that the modified Shanks’ conjecture reported by Jury was valid for special classes of 2-D polynomials. …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,035 accessesView PDF Cite
