Signal Systems

Signal systems are organized methods for transmitting information across networks, such as transportation, communication, or electrical systems. They use signals—like lights, sounds, or electronic pulses—to control, coordinate, and ensure safe operation of devices or processes. For example, traffic lights manage vehicle flow, while railway signals prevent collisions. These systems rely on a combination of sensors, controllers, and communication channels to monitor conditions and make real-time decisions, enhancing efficiency and safety across various industries.
