Which technique focuses on mapping the flow of power and information through a system?

• A. Block Diagrams
• B. Bracketing
• C. Signal Flow
• D. Information Funneling

Answer: (C)

Mapping how power and control signals travel through a system is what signal flow diagrams are all about. This technique lays out the actual paths from sources through processing stages to destinations, using arrows to show the direction of information and power flow. In motor control, you can trace how a sensor input or command moves into the controller, how the controller’s decisions drive the actuator, and how the result feeds back, giving you a clear picture of the sequence and dependencies in the system. That explicit focus on the route and direction of both signals and power is what makes signal flow the best fit here. Block diagrams show relationships between functional blocks but not the detailed flow paths, bracketing isn’t about flow mapping, and information funneling isn’t a standard technique for this purpose.
