Challenge Problems

Push your limits with challenges.

Question 1

A system has a gain of 250 and a feedback factor of 0.04. What is the new output voltage if the input is 50 mV?

💡 Hint: Use feedback gain calculations as previously discussed.

Question 2

If an amplifier with a feedback factor of 0.1 has an input resistance of 5 kΩ, how much does the input resistance change with feedback?

💡 Hint: Incorporate the desensitization factor for input resistance.
