Challenge Problems
Push your limits with advanced challenges
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.
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.
