Show hintHide hint
Think about how you quantify the output compared to input.
Question 2.
What is negative feedback?
Show hintHide hint
Consider what happens to the gain.
3Question 3.
What does forward amplifier gain measure?
- Output to input power
- Output voltage to input current
- None of the above
Show hintHide hint
Reflect on how gain is quantified in amplifiers.
4Question 4.
True or False: Negative feedback only reduces gain.
- True
- False
Show hintHide hint
Think about the overall benefits of feedback.
Question 5.
Given a circuit with specific resistances for input and feedback, derive the overall forward gain, Z_m. Then analyze how adjusting the feedback resistor impacts the gain.
Show hintHide hint
Consider the equations relating feedback to gain.
Question 6.
