WebNegative feedback definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. Look it up now! Negative feedback takes some of the output signal of a system or device and feeds it back to its input. Negative feedback reduces the high open-loop gain of a system or device reducing distortion, noise and instability while improving bandwidth. Negative feedback is commonly used in amplifier systems where … See more If the open-loop gain, G is very large, then βG will be much greater than 1, so that the overall gain of the system is roughly equal to 1/β. If the open-loop gain decreases due to frequency or the … See more A system has a gain of 80dB without feedback. If the negative feedback fraction is 1/50th. Calculate the closed-loop gain of the system in dB with the addition of negative feedback. Then we can see that the system has a loop … See more Operational amplifiers (op-amps) are the most commonly used type of linear integrated circuit but they have a very high gain. The open-loop … See more If after 5 years the loop gain of the system without negative feedback has fallen to 60dB and the feedback fraction has remained constant at … See more
