  13. Automatic control Mason’s Rule Mason’s gain rule is as follows: the transfer function of a system with signal-input, signal-output flow graphs is Δ=1-(sum of all loop gains)+(sum of products of gains of all combinations if 2 nontouching loops)- (sum of products of gains of all combinations if 3 nontouching loops)+… A path is any succession of branches, from input to output, in the direction of the arrows, that does not pass any node more than once. A loop is any closed succession of branches in the direction of the arrows that does not pass any node more than once. Automatic Control by Meiling CHEN
