Question 1
What is the desensitivity factor formula?
- D = (1 - βA)
- D = (1 + βA)
- D = β/A
💡 Hint: Look at how feedback modifies the gain.
Question 2
True or False: The desensitivity factor increases system sensitivity.

Challenge Problems
Push your limits with challenges.
Question 1
Design a negative feedback amplifier circuit that integrates a feedback factor of β = 0.1, and forward gain A = 10. Calculate the desensitivity factor.
💡 Hint: Use the formula for desensitivity factor carefully, utilize given numbers correctly.
Question 2
Create a scenario where increasing feedback results in significant stability improvement in a control system.
💡 Hint: Think about how adjustments in one area create stability in another.
