Dual non-negative rational symbols with arbitrary approximation order / Cotronei, M., LO CASCIO, M.L., Sauer, T.. - In: APPLIED NUMERICAL MATHEMATICS. - ISSN 0168-9274. - 51:(2004), pp. 497-510. [10.1016/j.apnum.2004.06.006]
Abstract:
We consider the construction of dual filters with a prescribed approximation order, that is with the ability to
reproduce polynomials up to a certain degree. Specifically, we illustrate how to construct nonnegative duals when
starting from a nonnegative primal filter. This construction produces filters with rational symbol, which can then
be either implemented efficiently as recursive IIR filter or approximated by a Laurent polynomial.
