Context?
1. Negative feedback can increase linearity at the expense of losing gain. 2. & 3. Positive feedback can result in large increases in gain until the increases becomes so large that oscillation occurs. 4. Positive or negative feedback at one frequency can result in enhanced or decreased response to that frequency.
The thermal stability is the ability of the transistor to withstand changes in temperature without the transistor's parameters changing. Transistors generally have poor thermal stability and in particular the Beta parameter increases with temperaure, which can cause thermal runaway in a badly designed circuit. This is well known and the bias current in transistors is normally stabilised by the application of negative feedback in proper circuit design.

it is the amount by which instrument's sensitivity varies as ambient conditions change.
emitter follower is a type of negative feedback ,
Feedback can cause a lack of stability. However, negative feedback can actually reduce distortion, noise, and sensitivity to the noise.
What is meaning of Transformer sensitivity?
[1/(1+Ab)] is the expression for sensitivity...
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
Stability of a given system
A: Stability
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
posistive feedback
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
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
The fin
Most people play on sensitivity 3-5, but alot prefer 4 for its quick control that still provides stability.
