Feedbacks vs. Feedback — What's the Difference?

(proscribed) feedback

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. The system can then be said to feed back into itself.

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.

Sound created when a transducer, such as a microphone or the pickup of an electric guitar, picks up sound from a speaker connected to an amplifier and regenerates it back through the amplifier.

The return of information about the result of a process or activity; evaluative response

The process by which a system, often biological or ecological, is modulated, controlled, or changed by the product, output, or response it produces.

Critical assessment of a process or activity or of their results.

The part of an output signal that is looped back into the input to control or modify a system.

The high-pitched howling noise heard when there is a loop between a microphone and a speaker.

(music) To generate the high-frequency sound by allowing a speaker to cause vibration of the sound generator of a musical instrument connected by an amplifier to the speaker.

(transitive) To provide informational feedback to.

(transitive) To convey by means of specialized communications channel.

The process in which part of the output of a system is returned to its input.

Response to an inquiry or experiment.

The process in which part of the output of a system is returned to its input in order to regulate its further output

Response to an inquiry or experiment
