feedback feed·back (fēd’bāk’)
The supply of an input to some process or system as a function of its output. See more at negative feedback, positive feedback.
Feedback in which the output quantity or signal adds to the input quantity or signal. Positive feedback is responsible for the squealing of microphones when placed too close to the speaker through which their input signals are amplified. Compare negative feedback.
A process in which a system regulates itself by monitoring its own output. That is, it “feeds back” part of its output to itself. Feedback is used to control machines; a heating system, for example, uses a thermostat to monitor and adjust its output. Feedback is also used by the human brain to control various muscles and joints.
Note: By extension, “feedback” is any response or information about the result of a process.
Note: Feedback is usually a feature of automation.
