Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier with a pole at s = -2, calculate the new frequency response when negative feedback with β = 0.4 is applied.
💡 Hint: Use the equation for pole shifting with feedback.
Question 2
Analyze how changing from negative feedback to positive feedback (β > 1) affects stability for an amplifier with two poles at s = -2 and s = -4.
💡 Hint: Consider how the system's response changes under different feedback types.
