signal systems
Signal systems are methods used to convey information through various forms of signals. These signals can be visual, auditory, or electronic, and they help in communication across different fields, such as telecommunications, transportation, and computer networks. For example, traffic lights are a simple signal system that uses colored lights to direct vehicle and pedestrian movement.
In telecommunications, signal systems enable the transmission of data over distances. This includes technologies like radio waves, fiber optics, and satellite communication. Each system has its own way of encoding and decoding information, ensuring that messages are accurately sent and received between devices or locations.
