Question 1
What does negative feedback do to the pole of an amplifier?
- Shifts it to a higher frequency
- Shifts it to a lower frequency
- Does not affect it
π‘ Hint: Consider how feedback impacts the amplifier's performance.
Question 2
True or False: The loop gain is the product of the forward gain and feedback factor.
- True
- False
π‘ Hint: Recall the formula for loop gain in a feedback system.

Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier with a low-frequency gain of 10 dB and Ξ² = 0.5, calculate the new pole location after feedback is applied.
π‘ Hint: Make sure to convert gain from dB to a linear scale before using it in the equation.
Question 2
Analyze how changing the feedback factor Ξ² from 0.1 to 0.9 affects the stability of a single-pole system.
π‘ Hint: Consider how the new pole shifts as Ξ² changes and its impact on system response.
