A signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, but often called a Mason graph after Samuel Jefferson Mason who coined the term, is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional … See more Wai-Kai Chen wrote: "The concept of a signal-flow graph was originally worked out by Shannon [1942] in dealing with analog computers. The greatest credit for the formulation of signal-flow graphs is normally extended to See more Robichaud et al. identify the domain of application of SFGs as follows: "All the physical systems analogous to these networks [constructed of ideal transformers, active elements and gyrators] constitute the domain of application of the … See more For some authors, a linear signal-flow graph is more constrained than a block diagram, in that the SFG rigorously describes linear algebraic equations represented by a directed graph. For other authors, linear block diagrams and linear signal … See more Signal-flow graphs can be used for analysis, that is for understanding a model of an existing system, or for synthesis, that is for determining the properties of a design alternative. See more The following illustration and its meaning were introduced by Mason to illustrate basic concepts: In the simple flow graphs of the figure, a functional … See more Linear signal-flow graph (SFG) methods only apply to linear time-invariant systems, as studied by their associated theory. When modeling a system of interest, the first step is often to determine the equations representing the system's operation without … See more The term "cause and effect" was applied by Mason to SFGs: "The process of constructing a graph is one of tracing a succession of cause and effects through the … See more WebJul 1, 2024 · A) In the signal flow graph signals travel along branches only in the marked direction. B) Nodes are arranged from right to left in a sequence. C) Signal flow graphs applicable for the LTI system only. D) For signal flow, the algebraic equation must be in the form of cause and effect.

WebThe signal-flow graph and computation graph shown in Figure 7.7 represent the operations that must be executed during a single sample interval. However, the DSP algorithm will, in principle, be executed repeatedly. From a computational point of view, the repeated execution of the algorithm can be represented by an infinite sequence of computation … WebA signal flow graph is the graphical representation of the relationships between the variables of set linear algebraic equations.
