Question 1
What does the feedback factor (β) represent?
- The input voltage
- The output voltage
- The portion of output fed back to the input
💡 Hint: Consider its role in the feedback loop.
Question 2
True or False: Negatively feeding back signals always increases product volatility.
- True
- False
💡 Hint: Think about feedback's purpose in amplification.

Challenge Problems
Push your limits with challenges.
Question 1
Design a feedback system with an initial gain of 50. If the feedback factor decreases output performance by 10%, what would the new gain be?
💡 Hint: Consider how feedback alters performance.
Question 2
Evaluate the effect of reducing feedback by half on an amplifier's output resistance that initially was 200 Ω.
💡 Hint: Refer to the principles of feedback effects on resistance.
