Feedback is a phenomenon which occurs when outputs of a system are routed back as inputs.
Description
This process of outputs becoming inputs forms a signal chain of cause-and-effect.
The system can then be said to feed back into itself, forming a closed circuit or loop.
Cause and effect
The notion of cause-and-effect has to be handled carefully when applied to feedback systems:
"Simple causal reasoning about a feedback system is difficult because the first system influences the second and second system influences the first, leading to a circular argument. This makes reasoning based upon cause and effect tricky, and it is necessary to analyze the system as a whole."
