Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier with a pole at -2+j4 and a feedback factor of 0.1, calculate the new pole location after feedback.
💡 Hint: Substitute the current location and feedback value in the formula.
Question 2
A two-pole system has poles at -1 and -10. If a feedback network applies a β value of 0.5, analyze the impact on the response characteristics.
💡 Hint: Calculate each pole's new position and analyze stability.
