Abstract
It is well-known that the vector fitting algorithm suffers from convergence problems when fitting noisy frequency responses. These difficulties are caused by the use of a Sanathanan-Koerner iteration. This paper presents an alternative iteration framework, applied to the orthonormal vector fitting technique. The convergence properties of this method are analysed and compared to the classical vector fitting iteration schemeFile in questo prodotto:
