The most common technique used for modeling linear, time-invariant systems is the block diagram, with the mathematical model represented as a transfer function. As an example of the first situation - ...

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 ...

To represent the more complicated system into more simplified form and to interpret different physical and mechanical systems we need a block diagram representation technique. The Routh-Hurwitz ...
