Consider the following statements
1. The feedback can improve stability or can be harmful to stability.
2. Due to feedback, always the gain of the system will be reduced.
3. The output of the negative feedback closed-loop control system is more sensitive to feedback path parameter changes than the forward path parameter changes.
4. Negative feedback usually, reduces noise, decreases the bandwidth, and improves sensitivity.
