Challenge Problems
Push your limits with challenges.
Question 1
If an amplifier has a gain of 50 and feedback factor Ξ² = 0.1, what will be the gain after feedback is implemented? Further, illustrate this with a Bode plot showing both original and feedback gain.
π‘ Hint: Make sure to plot the frequencies correctly on a logarithmic scale.
Question 2
Discuss a scenario where two poles in a feedback amplifier can lead to instability and how to resolve this issue in design.
π‘ Hint: Think about how design choices affect stability in feedback systems.
