Question 1.
What is feedback in the context of amplifiers?
Show hintHide hint
Think about the relationship between input and output signals.
Question 2.
Name one effect of negative feedback on amplifier gain.
Show hintHide hint
Consider how the output influences the input.
3Question 3.
What effect does negative feedback have on amplifier gain?
- Increases gain
- Reduces gain
- No effect on gain
Show hintHide hint
Consider the mechanisms of regulating gain.
4Question 4.
True or False: Feedback can never improve circuit stability.
- True
- False
Show hintHide hint
Think about benefits of returning output to input.
Question 5.
Consider an amplifier with a gain of 10 and a feedback factor of 0.1. Calculate the new pole location given an original pole at 5 rad/s.
Show hintHide hint
Use the formula for the new pole location discussed in class.
Question 6.
Evaluate the effect of negative feedback on stability when an amplifier originally has poles at 3 and 8 rad/s and a feedback factor of 0.2.
Show hintHide hint
Keep in mind how feedback modifies both poles based on their interactions.
