Its feedback section quickly overflowed with righteous indignation.
Have you heard any feedback from Donatella or the Versace team?
The feedback loop has driven the scale, and stakes, of the humble college road trip to monster proportions.
feedback feed·back (fēd'bāk')
The return of a portion of the output of a process or system to the input, especially when used to maintain performance or to control a system or process.
The portion of the output so returned.
The return of information about the result of a process or activity.
The supply of an input to some process or system as a function of its output. See more at negative feedback, positive 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.
To surprise and create discomposure: those grades don't faze her (1830+)
Part of a system output presented at its input. Feedback may be unintended. When used as a design feature, the output is usually transformed by passive components which attenuate it in some manner; the result is then presented at the system input.
Feedback is positive or negative, depending on the sign with which a positive change in the original input reappears after transformation. Negative feedback was invented by Black to stabilise vacuum tube amplifiers. The behaviour becomes largely a function of the feedback transformation and only minimally a function of factors such as transistor gain which are imperfectly known.
Positive feedback can lead to instability; it finds wide application in the construction of oscillators.
Feedback can be used to control a system, as in feedback control.
