Question 1
An amplifier with a gain of 1200 has a bandwidth of 30 kHz. If a feedback factor of 0.03 is applied, what will the new closed-loop bandwidth be?
💡 Hint: Use the BW formula to calculate the result.
Question 2
Discuss the impact of increasing the feedback factor on bandwidth and gain in terms of amplifier performance in a design context.
💡 Hint: Refer back to key formulas and their implications.
