Question 1.
What is the primary effect of negative feedback on input resistance?
Show hintHide hint
Consider the relationship between input resistance and signal loading.
Question 2.
Define input resistance in your own words.
Show hintHide hint
Think about how a signal behaves when it enters the circuit.
3Question 3.
How does negative feedback typically affect input resistance?
- Increases it
- Decreases it
- No effect
Show hintHide hint
Remember the relationship we established in class regarding feedback mechanisms.
4Question 4.
True or False: Feedback reduces the output resistance of an amplifier.
- True
- False
Show hintHide hint
Think about feedback's role in enhancing performance.
Question 5.
Given an ideal amplifier with R_in = 10kΩ and a feedback factor of β = 0.2 and gain A = 50, calculate R_in_f.
Show hintHide hint
Follow the formula and substitute values carefully to verify your results.
Question 6.
