Gain Phase Theory

Gain Phase Theory is a concept primarily from engineering and control systems that describes how a system responds to input signals over time. It focuses on two key aspects: gain, which indicates how much the output signal is amplified compared to the input, and phase, which refers to the timing difference between the input and output signals. Understanding these aspects helps in designing systems that behave predictably, ensuring stability and performance. In broader contexts, it can be applied to various fields, including economics and communications, where the relationship between input and output dynamics is crucial.
