Question 1.
What happens to input resistance when negative feedback is applied?
Show hintHide hint
Think about the relationship: R_in_f = R_in (1 + βA).
Question 2.
Define load resistance in the context of feedback systems.
Show hintHide hint
It helps to think of loads in terms of their effect on voltage.
3Question 3.
What does feedback do to input resistance?
- Decreases it
- Increases it
- No effect
Show hintHide hint
Refer to the relation R_in_f = R_in (1 + βA).
4Question 4.
True or False: Load resistance always has no effect on circuit performance.
- True
- False
Show hintHide hint
Consider the implications of connecting devices.
Question 5.
Design a feedback circuit with specific input and output resistances and compute the effects of a finite load resistance on the overall performance.
Show hintHide hint
Break down the problem into measurable components.
Question 6.
Discuss the implications on system performance when both load resistance and feedback network resistances are significant.
Show hintHide hint
Use diagrams and equations to represent relationships clearly.
