We propose a new rule, loop reversal, in block diagram and signal flow graph manipulation (or transformation) that leads to equivalent block diagrams or signal flow graphs from existing ones. It is ...

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 ...

Transfer functions of linear systems, block diagrams and signal flow graphs. Sensitivity, control of transient response, disturbance signals. Time domain performance: steady state errors, performance ...
