Question 1
What is the primary effect of feedback on an amplifier's frequency response?
- It decreases the input impedance
- It stabilizes the gain
- It always increases the gain
💡 Hint: Reflect on how amplifiers maintain their output performance.
Question 2
True or False: Feedback can destabilize an amplifier if not properly implemented.
- True
- False
💡 Hint: Consider the behavior of systems under external modifications.

Challenge Problems
Push your limits with challenges.
Question 1
Design a feedback amplifier given specific initial gain and pole locations. How would you modify its structure to enhance stability?
💡 Hint: Use the transfer function to determine how varying feedback affects pole locations.
Question 2
Consider a dual-pole amplifier where both poles are close to the instability threshold. What feedback modifications could you propose to rectify this?
💡 Hint: Evaluate the relationship of gain versus frequency response to decide on suitable compensatory actions.
