✦ Synopsis

In this paper a method is presented which allows one to generate a/l basic signal flow graphs (SFG) ,for a given decomposition of the denominator of a biquadratic section. This approach is based on a binodal representation of u RC network with operational amplifiers (op amp) and classification of biquadrutic sections. The classification is made with respect to a type of the SFG representation and a type of the passive RC circuits associated with rhe op amp. A program has been written for an exhaustive generation of graphs representing the assumed decomposition of the denominator. The circuits have identical properties with respect to passive elements.
