Challenge Problems
Push your limits with challenges.
Question 1
If an amplifier has a gain of 50 and a feedback factor of 0.2, find the adjusted gain and verify if it leads to stability.
💡 Hint: Use the feedback gain formula.
Question 2
Given an amplifier with two poles at -3 Hz and -7 Hz, calculate the changes in pole locations with a feedback factor of 0.15 for both.
💡 Hint: Apply the feedback factor to each pole.
