An effect that occurs when the output of a DSP process is fed back into the input Interesting effects can result when you delay a signal, feed it through a non-linear process such as a filter or power distortion, and route it back to the input See feedback loop
the information and recommendations provided to a teacher about his/her performance based on the results of that teacher's evaluation and designed to help the teacher improve his/her performance and make decisions concerning professional development and improvement See Reporting
The return of information from a manipulator, or sensor to the processor of the robot to provide self-correcting control of the manipulator See Feedback Control, and Feedback Sensor
Feedback consists of text or images provided by the instructor for the student to view after a quiz has been scored Feedback can only be provided on a "per question" basis (not on a "per answer choice" basis) and is entered by the instructor on one of the "Create Question" screens Feedback is an excellent way to provide students with the appropriate corrections or suggestions if they answer a question incorrectly It can also provide additional reinforcement when students choose the correct answers For example, after the question "Who was the 16th president of the United States?," a possible feedback response could be "Please refer to Appendix C in your textbook for a complete list of the U S presidents " For additional information about where to enter feedback, read Question Types When inserting HTML into the feedback, please refer to the HTML included in the glossary
Energy that is extracted from a high-level point in a circuit and applied to a lower level Positive feedback reduces the stability of a device and is used to increase the sensitivity or produce oscillation in a system Negative feedback, also called inverse feedback, increases the stability of a system as the feedback improves stability and fidelity
The delaying of a delay so that multiple images of the original signal are heard; also, the loud squeal that's heard when a channel is receiving its own output
Using all or a portion of the information from the output of a system to regulate or control the processes or inputs in order to modify the output
The process by which a system responds to an initial forcing in such a way that it amplifies the original force (positive feedback) or reduces it (negative feedback)
A loop caused by audio or video signal being fed back into itself In video the effect is caused when a camera is directed at its receiving monitor In audio the effect, manifested as an echo or squeal, is caused when a microphone is aimed at a speaker
the process in which part of the output of a system is returned to its input in order to regulate its further output
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects 2) The pickup of the signal out of a channel by its input or the howling sound that this produces 3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise
The transmission of evaluation findings to parties for whom it is relevant and useful so as to facilitate learning This may involve the collection and dissemination of findings, conclusions, recommendations and lessons learned from experience Specifically in the context of evaluation, to return and share the evaluation results with those who participated in the evaluation
gen Product response (e g , visual, aural, or tactile) that indicates the extent to which the operator's desired effect was accomplished Feedback can be either intrinsic or extrinsic Intrinsic feedback (feel) is that which the individual senses directly from the operation of the control devices (e g , clicks, detents, resistance, response ratios, stops, control displacement ) Extrinsic feedback is that which is sensed from an external source that indicates the consequences of the control action (e g , aural tones, display changes, indicator lights) [MIL-HDBK-1908B]
Refers to the specific method used in ABR to tell a transmitting end station to slow down due to congestion in the network
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
1 The return of a portion of the output of a device to the input; positive feedback adds to the input, negative feedback subtracts for the input
