Using mesh rules, node rules and Ohm’s equations a signal flow graph can be build.

Moreover, it is always useful to develop a common graphical model, with using this model to make a connection between the state variables (parameters) and the transfer function as well as to obtain a better understanding of the complex functionality of a network. These methods are generally time-consuming and computationally intensive. There are various methods in the circuit technology to ca1culate transfer functions of electrical circuits such as Kirchhoff’s laws, two-port network theory, nodal analysis method and time constant method. In Boolean algebra, these 1-edges are given the value 1, whereas this value can be identified with a zero in the field algebra. If these two graphs are superposed with one another, so called 1-edges are created at the node points. The other half of the solution is the so-called identity, which represents the (SFG −1). Two signal flow graphs are always generated from one circuit, so that the signal flow diagram already presented in previous sections corresponds to only half of the solution. A signal flow graph can be verified by generating the identity of the signal flow graph itself, illustrated by the inverse signal flow graph (SFG −1). In this work we show you in addition: How we check our SFG whether it is a consistent system or not. In addition, the mathematical axioms, which are based on field algebra, are declared. During creation of a SFG the Direct Current-Case (DC-Case) was observed since the correct current and voltage directions was drawn from zero frequency. A Signal Flow Graph (SFG) allows a fast and practical network analysis based on a clear data presentation in graphic format of the mathematical linear equations of the circuit. Furthermore such a presentation allows for a clear and unambiguous description of a generating system, for example, a netview. The SFG allows a good visual inspection into complex feedback problems. In this case, the result is sent to the outgoing node.

The edges of the signal flow graph are small processing units, through which the incoming signals are processed in a certain form. A signal-flow graph describes a system by its signal flow by directed and weighted graph the signals are applied to nodes and functions on edges. In this work a method called “signal flow graph (SFG)” is presented.
