Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
A: DEFINITELY NOT Open loop is defined as no feedback. any kind of negative feedback will reduce the gain
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
A: It is any system where there is negative feedback to control its behavior
Because a negative feedback system "closes the loop" based on a temperature sensor in the tip of the iron. This makes the temperature of the iron nearly constant whether sitting idle on the stand or being used to solder a massive joint. Without this negative feedback the temperature of the open loop iron would rise significantly when sitting idle on the stand and fall significantly when being used to solder a massive joint.

A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
In general, the transfer function of closed loop system is (Y/X)=G*K/(1+G*K*H) ----- negative feedback (Y/X)=G*K/(1-G*K*H) ----- positive feedback where G- transfer function of the plant 0r system K - controller H - feedback transfer function Y-output in laplace domain X-reference in laplace domain so the transfer function of the closed loop system with unity feedback is so H=1(unity) (Y/X)=G*K/(1+G*K) ------- negative feedback (Y/X)=G*K/(1-G*K) ------- positive feedback if u couldn't understand notify me... i will improve it
Feedback oscillators have a closed loop gain of
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.

They are either in closed or in open loop system
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
This is known as a feedback loop. When a system's output influences its input in a way that reduces the output, it can lead to the system shutting down or destabilizing. This feedback loop can have either positive (amplifying) or negative (stabilizing) effects on the system.
A Negative Feedback Loop.
Negative feedback is necessary in closed-loop control systems to ensure the system remains stable and responsive to changes. It helps to detect and correct errors, minimizing deviations from the desired output. By providing a means to compare the actual output to the desired reference input, negative feedback allows for adjustments to be made to keep the system operating within desired parameters.
