Abstract :
Presents a method for the design of an IIR digital filter with real coefficients that approximates an arbitrary complex-valued frequency response. The iterative procedure is characterized by desirable convergence properties and has been observed to yield substantially better filters than other approaches. The method has been designed to be robust, easy to implement, widely applicable, and extremely efficient. The computational requirement of the algorithm is O(N3) for the design of a filter with N coefficients
