Question 1.
What is the formula for the desensitivity factor?
Show hintHide hint
Remember it relates feedback to amplifier gain.
Question 2.
Define feedback in an amplifier system.
Show hintHide hint
Think about stability and consistency.
3Question 3.
What is the desensitivity factor formula?
- D = (1 - βA)
- D = (1 + βA)
- D = β/A
Show hintHide hint
Look at how feedback modifies the gain.
4Question 4.
True or False: The desensitivity factor increases system sensitivity.
- True
- False
Show hintHide hint
Think about stability and changes in input.
Question 5.
Design a negative feedback amplifier circuit that integrates a feedback factor of β = 0.1, and forward gain A = 10. Calculate the desensitivity factor.
Show hintHide hint
Use the formula for desensitivity factor carefully, utilize given numbers correctly.
Question 6.
Create a scenario where increasing feedback results in significant stability improvement in a control system.
Show hintHide hint
Think about how adjustments in one area create stability in another.
