Feedback can cause a lack of stability. However, negative feedback can actually reduce distortion, noise, and sensitivity to the noise.
Context?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
A: Number one it provide stability for the amplifier or system. The greater the feedback the greater the stability but less gain. In other words gain is inversely related to feedback
What is meaning of Transformer sensitivity?
1.feedback in control system improves the speed of response2.using feedback in control system we can reduce the sensitivity of the system to parameter variation
[1/(1+Ab)] is the expression for sensitivity...
Stability of a given system
A: Stability
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
Most people play on sensitivity 3-5, but alot prefer 4 for its quick control that still provides stability.
Feedback Inhibition
damage to the fovea would have the least effect on visual sensitivity to what stimuli
