Challenge Problems
Push your limits with advanced challenges
Given a circuit with a forward amplifier gain of 10 and a loop gain of -4, analyze the overall gain.
💡 Hint: Focus on the impact of feedback characteristic here.
Evaluate how a system with positive feedback fails during an oscillation test at various frequencies.
💡 Hint: Compare each frequency's response—oscillation should increase if feedback is positive.
