= Mason equation
{wiki=Mason_equation}
The Mason equation, also known as Mason's gain formula, is a fundamental concept in control theory and signal flow analysis, particularly in the context of electrical engineering and systems analysis. It provides a systematic method to determine the transfer function of a linear time-invariant (LTI) system represented as a signal flow graph. In a signal flow graph, systems are represented as nodes (variables) and directed edges (dependencies between variables).
