F f - noun feedback Information about reactions to a product, a person's performance of a task, etc., used as a basis for improvement. 1
- noun Definition of feedback in Technology (electronics) 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. 1
- noun feedback high-pitched noise from loudspeaker 1
- noun feedback science: modification by results 1
- noun feedback opinion, criticism 1
- noun feedback Electronics. the process of returning part of the output of a circuit, system, or device to the input, either to oppose the input (negative feedback) or to aid the input (positive feedback) acoustic feedback. 1
- noun feedback the furnishing of data concerning the operation or output of a machine to an automatic control device or to the machine itself, so that subsequent or ongoing operations of the machine can be altered or corrected. 1
- noun feedback a reaction or response to a particular process or activity: He got very little feedback from his speech. 1
- noun feedback evaluative information derived from such a reaction or response: to study the feedback from an audience survey. 1
- noun feedback Psychology. knowledge of the results of any behavior, considered as influencing or modifying further performance. Compare biofeedback. 1
- noun feedback Biology. a self-regulatory biological system, as in the synthesis of some hormones, in which the output or response affects the input, either positively or negatively. 1
- noun feedback Critical assessment on information produced. 0
- noun feedback (cybernetics, systems) The signal that is looped back to control a system within itself. 0
- noun feedback The high-pitched howling noise heard when there's a loop between a microphone and a speaker. 0
- verb feedback (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. 0
- verb feedback (Transitive Verb) To provide informational feedback to. 0
- verb feedback (Transitive Verb) To convey by means of specialized communications channel. 0
- uncountable noun feedback If you get feedback on your work or progress, someone tells you how well or badly you are doing, and how you could improve. If you get good feedback you have worked or performed well. 0
- uncountable noun feedback Feedback is the unpleasant high-pitched sound produced by a piece of electrical equipment when part of the signal that comes out goes back into it. 0
- noun feedback the return of part of the output of an electronic circuit, device, or mechanical system to its input, so modifying its characteristics. In negative feedback a rise in output energy reduces the input energy; in positive feedback an increase in output energy reinforces the input energy 0
- noun feedback that part of the output signal fed back into the input 0
- noun feedback the return of part of the sound output by a loudspeaker to the microphone or pick-up so that a high-pitched whistle is produced 0
- noun feedback the whistling noise so produced 0
- noun feedback the effect of the product of a biological pathway on the rate of an earlier step in that pathway 0
- noun feedback the substance or reaction causing such an effect, such as the release of a hormone in a biochemical pathway 0
- noun feedback information in response to an inquiry, experiment, etc 0
- verb feedback to return (part of the output of a system) to its input 0
- verb feedback to offer or suggest (information, ideas, etc) in reaction to an inquiry, experiment, etc 0
- noun feedback the transfer of part of the output of an active circuit or device back to the input, either as an unwanted effect or in an intentional use, as to reduce distortion 0
- noun feedback a process in which the factors that produce a result are themselves modified, corrected, strengthened, etc. by that result 0
- noun feedback a response, as one that sets such a process in motion 0
- noun feedback Feedback is a type of control in which the error is considered when deciding future control actions. 0
- noun feedback Feedback is the process of part of the signal coming out of a piece of electrical equipment going back into it to reduce or increase the amplification. 0
