Challenge Problems
Push your limits with challenges.
Question 1
Given an amplifier with a voltage gain of 100, applying feedback reduces this by desensitization factor 5. Calculate the new voltage gain.
π‘ Hint: Simplify the gain according to the factor.
Question 2
You have a circuit where the input resistance increased from 1kΞ© to 5kΞ© after feedback. What does this indicate about the circuit?
π‘ Hint: Consider the implications for the amplifier's performance with loading.
