Question 1.
Define feedback system.
Show hintHide hint
Think about systems regulating themselves.
Question 2.
What is negative feedback?
Show hintHide hint
It's the type of feedback used to stabilize circuits.
3Question 3.
What type of feedback stabilizes the circuit?
- Positive Feedback
- Negative Feedback
- Both
Show hintHide hint
Consider which feedback approach works against input changes.
4Question 4.
True or False: Positive feedback always creates stable systems.
- True
- False
Show hintHide hint
Reflect on examples where oscillations occur.
Question 5.
Given a circuit with a forward amplifier gain of 10 and a loop gain of -4, analyze the overall gain.
Show hintHide hint
Focus on the impact of feedback characteristic here.
Question 6.
Evaluate how a system with positive feedback fails during an oscillation test at various frequencies.
Show hintHide hint
Compare each frequency's response—oscillation should increase if feedback is positive.
