Signal Flow Analysis

Definition

Signal flow analysis is a method used to analyze the behavior of signals in a system by focusing on the flow and transformation of these signals through various components. This approach helps in understanding how different parts of a system interact and influence each other, making it easier to predict system performance and detect issues. It is particularly relevant in structural modeling, where understanding the interconnections between components is crucial for design and verification.
