What is a feedback system? Split and merge into it. Answer by Arkay. Confidence votes 37. A feedback system, in general engineering terms, is a system whose output if fed back to the input, and depending on the output, your input is adjusted so as to reach a steady-state.

How to Control Feedback in a Sound System What causes it. The simplest PA system consists of a microphone, an amplifier and one or more speakers. Whenever you have those three components, you have the potential for feedback. Here’s an example: Let’s say that that you place the microphone in front of the speaker as shown here.

Positive and negative feedback systems? Answers. 1  There are actually countless feedback loops in the human body, so it would be quite difficult to pinpoint them all. Generally, though, positive feedback loops cause some kind of amplification, and negative feedback loops work to maintain conditions at a certain level. Furthermore, negative feedback loops generally work to shut themselves off, whereas positive feedback loops must be shut off by a different set of mechanisms. An example of a positive feedback system would be blood clotting. When you get injured, the damaged tissue releases chemical signals that activate platelets. These platelets release chemicals that activate other platelets, and so on and so forth, until lots and lots of platelets are activated and clots form. Once the clotting has been taken care of, separate signals are used to shut off the cascade. Negative feedback occurs in a lot of processes that maintain homeostasis.

Regulation - It's All About Homeostasis Negative feedback is a process that happens when your systems need to slow down or completely stop a process that is happening. When you eat, food travels into your stomach, and digestion begins. You don't need your stomach working if you aren't eating.

Positive feedback Positive feedback is a process that occurs in a feedback loop in which the effects of a small disturbance on a system include an increase in the magnitude of the perturbation. That is, A produces more of B which in turn produces more of A.

feedback (ˈfiːdˌbæk) n. 1. (Electronics) a. 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.

- In closed loop control systems current output is taken into consideration and corrections are made based on feedback. A closed loop system is also called a feedback control system. The human body is a classic example of feedback systems.

Feedback A feedback loop where all outputs of a process are available as causal inputs to that process. 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.

What is feedback in communication? feedback is the response by the source to determine if the message has been receiver and understood thus after the receiver has decodes and interpreted a message then becomes the sourced also vital part in communication because it enables the original source to evaluate how the receiver has received his.

- In a positive feedback loop, pertur-bations cause the effector to drive the value of the con-trolled variable even farther from the set point. Hence, sys-tems in which there is positive feedback are highlyunstable, analogous to a spark that ignites an explosion.They do not help to maintain homeostasis.

feedback Related Terms. Process in which the effect or output of an action is 'returned' (fed-back) to modify the next action. Feedback is essential to the working and survival of all regulatory mechanisms found throughout living and non-living nature, and in man-made systems such as education system and economy. As a two-way flow, feedback is inherent to all interactions, whether human-to-human, human-to-machine, or machine-to-machine.

definitions - feedbackreport a problem Ramaprasad (1983) defines feedback generally as information about the gap between the actual level and the reference level of a system parameter which is used to alter the gap in some way, emphasising that the information by itself is not feedback unless translated into action.
