Introduction to output signal
The output signal is the result of the input and processing of the system or the information service it can provide. It is a concept in cybernetics. In cybernetics, the connection between systems is divided into "input" and "output". The output signal can provide a switch signal when there is a control requirement to make the controlled device act. After the controller receives the input signal, according to the pre-programmed program, the controller transmits the linkage control signal to the output module through the bus, and the output module starts the equipment that needs linkage; after the device operates, it will receive a signal to answer.
