A feedback loop where all outputs of a process are available as causal inputs to that process. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause and effect that forms a circuit or loop. [1] The system can then be said to feed back into itself. The notion of cause-and-effect has to be handled ...
A sender and a recipient connected by a mailbox provider (MP). The feedback provider and the feedback consumer are the two formal endpoints of the feedback loop (blue arrow). Senders need to subscribe, possibly using a web form similar to the one depicted on the upper left corner, in order to become feedback consumers.
Example of a single industrial control loop; showing continuously modulated control of process flow. A closed-loop controller or feedback controller is a control loop which incorporates feedback, in contrast to an open-loop controller or non-feedback controller. A closed-loop controller uses feedback to control states or outputs of a dynamical ...
Positive feedback (exacerbating feedback, self-reinforcing feedback) is a process that occurs in a feedback loop which exacerbates the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. [ 1 ]

The system described in the Growth and Underinvestment Archetype consists of three feedback loops. Each feedback loop can be one of two types: [1] Reinforcing loop A reinforcing loop is a type of a feedback loop, where a positive increase of variable A causes an increase in variable B, which then in turn causes a positive increase in variable A ...
Feedback control loop, a closed-loop controller; Audio feedback, the "howl" sometimes heard in microphone or guitar amplification systems; Video feedback, the optical equivalent of audio feedback, caused when a camera films the image it is producing; Positive feedback, a feedback system that responds to perturbation in the same direction as the ...
