Feedback System - an overview ScienceDirect Topics

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.
