Negative+Feedback

Negative feedbacks tend to reduce the input signal that caused it, is also known as a self-correcting or balancing loop

EX.) The heating system in your home is a simple negative feedback circuit. When the furnace produces enough heat to elevate temperature above the set point of the thermostat, the thermostat is triggered and shuts off the furnace (heat is feeding back negatively on the source of heat). When temperature drops back below the set point, negative feedback is gone, and the furnace comes back on.
