sensory receptor
The sensor component of a negative feedback loop detects changing conditions and sends signals to the control center for regulating responses to maintain homeostasis.
Operational amplifiers (op-amps) use negative feedback in various electronic circuits to stabilize and control the gain. Negative feedback is employed to reduce distortion, increase bandwidth, and maintain precision in the output signal. It is a common technique used in amplifier, filter, and oscillator circuits to improve performance and stability.
Examples of feedback loops in the body include the regulation of blood sugar by insulin and glucagon, the maintenance of body temperature through sweating and shivering, and the control of breathing rate in response to changing oxygen levels. These feedback loops help maintain homeostasis and keep our body functioning properly.
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or interest generation among the clients) and a negative feedback means a bad response (unhappy clients, criticism and the like ).
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.

Feedback control is the process by which a system's output is monitored and used to adjust the system's input. This mechanism allows the body to regulate internal conditions within a narrow range, maintaining homeostasis. Negative feedback is a common type of control system where the system responds in a way that reduces the discrepancy between the desired and actual output.
An example of negative feedback in living organisms is the regulation of body temperature. When the body temperature rises above a set point, the body responds by sweating to cool down. Once the temperature returns to normal, the sweating stops, preventing the body from overheating.
A: It is any system where there is negative feedback to control its behavior
The sensor component of a negative feedback loop detects changing conditions and sends signals to the control center for regulating responses to maintain homeostasis.
Self-regulating control mechanisms usually operate by a process called negative feedback. Negative feedback helps to maintain stability within a system by detecting changes in a controlled variable and activating mechanisms to counteract those changes. This helps to keep the system within a desired range or setpoint.
A: A system ideally should have infinite gain but if that is so then it will saturate to one state or the other Feedback [negative] insure that will not happen the feedback will control the saturation making it stable.
assume it is accurate and strive to solve the parts of the problems you can control and forget about the parts you cannot control.
Negative feedback in a control system allows for the system to self-regulate and maintain stability by comparing the output with a desired set point. If the output deviates from the set point, the negative feedback mechanism adjusts the input to bring the system back to the desired state. This helps the system to maintain consistent performance and minimize errors.
