negative feedback teriminin İngilizce İngilizce sözlükte anlamı
feedback in which a portion of the signal from a later amplifier stage is fed back to an earlier stage (or to the same stage) in such a manner as to subtract from the input signal
Feedback that reduces the output of a system, such as the action of heat on a thermostat to limit the output of a furnace or the accumulation of toxic waste products by a growing population of bacteria
Change in the state of a system that counteracts the measured effect of the initial alteration
A portion of the output signal that is feed to the input (of an amplifier), out of phase
Feedback from the output of an analogue circuit that tends to oppose the input This has the effect of stabilising the circuit
The principle governing most control systems; a mechanism of response in which a stimulus initiates actions that reverse or reduce the stimulus
1) (circuits and systems) The process by which part of the signal in the output circuit of an amplifying device reacts upon the input circuit in such a manner as to counteract the initial power, thereby decreasing the amplification 2) (control) (industrial control) A feedback signal in a direction to reduce the variable that the feedback represents 3) (degeneration) (stabilized feedback) (data transmission) The process by which a part of the power in the output circuit of an amplifying device reacts upon the input circuit in such a manner as to reduce the initial power, thereby reducing the amplification (IEEE Std 100-1988)
In systems thinking, this is a process which acts to counter or "dampen" the potentially disruptive effects of external inputs; it acts as a stabilizing mechanism
mechanism process by which the "cause" of a change is lessened or dampened by its "effect "
An interaction that reduces or dampens the response of the system in which it is incorporated (Source: Carbon Dioxide Information Analysis Center, 1990)
If some of the output of an amplifier is made to be out of phase, and mixed back with the amp's input signal, it will partially cancel the input, reducing the gain of the amplifier; this is called negative feedback
A type of feedback in which a perturbation to a system causes a damping of the process, and thus opposes itself
