Feedback can always improve stability iii. In many situations the feedback can reduce the effect of noise and disturbance on system performance. iv. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

Correct Answer: i, iii and iv only
Negative feedback increases stability but not positive positive feedback reduces the stability and for this reason negative feedback systems are used.
