A recurring problem in feedback control theory is the determination of a system transfer function (as a Laplace transformed function of s), starting from a block diagram of the system. One commonly ...

Block diagrams and signal-flow graphs are used to represent and to obtain the transfer function of interconnected systems. The reduction of signal-flow graphs is considered simpler than the reduction ...

Mason.m uses mason's rule to simplify signal flow graphs. It takes a file describing the network and produces a symbolic equation relating a dependent output node to an independent input node. Mason's ...

Circuit equations are now algebra equations. This is possible because circuit equations depend on the circuit connectivity. Using impedance has not changed any circuit connections. Impedances also ...
