The negative feedback system

WebIn a Feedback System, all or part of the output signal either positive or negative is fed back to the input. Feedback Systems process signals and as such are signal processors. The processing part of a feedback system may be electrical or electronic, ranging from a very simple to a highly complex circuits. WebIn negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance. In this way, the concentration of hormones in blood is maintained within a …

WebJan 17, 2024 · Negative feedback mechanisms reduce output or activity to return an organ or system to its normal range of functioning. Regulation of blood pressure is an example of negative feedback. Blood vessels have sensors called baroreceptors that detect if blood pressure is too high or too low and send a signal to the hypothalamus. WebThe meaning of NEGATIVE FEEDBACK is feedback that tends to dampen a process by applying the output against the initial conditions.
