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
💡 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
💡 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 β = 0.5, calculate the new pole location after feedback is applied.
💡 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 β from 0.1 to 0.9 affects the stability of a single-pole system.
💡 Hint: Consider how the new pole shifts as β changes and its impact on system response.
