Arrow Notation

Definition

Arrow notation is a shorthand graphical representation used in control system analysis to simplify the expression of signal flow between components in block diagrams. It effectively conveys the direction of signals and the relationships between different elements, making it easier to analyze and reduce complex systems without getting lost in the details.
