21. The signal flow graph is further manipulated so that the gains into each summing node is + 1. 22. The result of all the manipulation is shown as the bottom signal-flow graph in the figure. 23. Another type of flow graph commonly used is the call graph, in which nodes correspond to entire subroutines. 24. An important kind of noncommutative signal-flow graph is a finite state automaton over an alphabet \ Sigma. 25. PACT programs are constructed as data flow graphs that consist of data sources, PACTs, and data sinks. 26. When required to have a single exit, flow graphs have two properties not shared with directed graphs in general. 27. Functions are represented by a control flow graph of basic blocks, using static single assignment ( SSA ) form. 28. Cyclomatic complexity is computed using the control flow graph of the program : the nodes of the classes within a program. 29. Perhaps the best known sub-class of flow graphs are control flow graphs, used in compilers and program analysis. 30. Perhaps the best known sub-class of flow graphs are control flow graphs , used in compilers and program analysis.
