El-Sayed Mostafa Saad, Amr E. Mohamed, Essam M. Shafei · European Conference on Circuit Theory and Design · 1989
Presents a method for designing high order (IIR) digital filters. The method is based on direct realization of high order filters in the form of cascaded sections of first and second orders. The obtained filter will fit the required one with good approximation. Examples are given to illustrate the method. >
