Frequency domain synthesis of IIR digital filters by means of associated FIR filters
M. Decina, F. Riciniello, Aldo Roveri · Proceedings of the IEEE · 1977
This correspondence describes a synthesis technique for IIR digital filters which allows the use of approximation methods already developed for designing FIR filters. The technique is based on the definition, by means of a suitable transformation, of a FIR filter associated to the desired IIR filter. An example of application is given and the related results are briefly discussed.
