Mason™s rule is useful for solving relatively complicated block diagrams by hand. It yields the solution in the sense that it provides an explicit inputŒoutput relationship for the system represented by the diagram. The advantage compared with path-by-path block-diagram reduction is that it is systematic and algorithmic rather than problem ...
