Which signal flow topology could include linear, divergent, or convergent paths and contains switches that can change the flow of the signal?

• A. Switched Path
• B. Signal Flow Graph
• C. Parallel Distribution
• D. Ring Topology

Answer: (A)

Switched path is the topology that uses switches to route a signal, letting the flow follow a straight line, split into multiple paths (divergent), or come together from different paths (convergent) depending on the switch settings. The switches are what enable reconfiguration of the signal’s path, so you can actively change how the signal travels through the system.

In contrast, a signal flow graph is mainly a diagram for analyzing relationships between signals with nodes and directed branches, not primarily about switching the physical route of the signal. Parallel distribution describes sending the same signal along multiple paths, typically in a fixed way, without the explicit switching control to re-route flows. Ring topology refers to a circular network layout, focusing on connectivity rather than switch-driven reconfiguration of signal paths.
