A control systems engineer is designing the safety shutdown logic for a high-pressure chemical reactor. Before implementing the physical hardware logic, they construct a truth table representing the state of the three input sensors (pressure, temperature, and bypass switch) and the resulting emergency valve activation signal.
Explain the purpose of a truth table in this system design process.
