Everything about Negative feedback
Control concept
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances. Wikipedia →

📖 Definitions
Noun A situation where some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
Noun A feedback loop in which the output signal of a system is amplified with a net negative gain and added to the input signal, before the main amplifier.
