Question 1.
What is a dominant pole?
Show hintHide hint
Think about which pole will influence the output the most.
Question 2.
Define a Bode plot.
Show hintHide hint
Consider how you visualize frequency responses.
3Question 3.
What is the main effect of feedback on system poles?
- They move closer together
- They become imaginary
- They become less influential
Show hintHide hint
Think about the changes feedback introduces.
4Question 4.
True or False: Real poles always guarantee system stability.
- True
- False
Show hintHide hint
Consider the implications of pole placement.
Question 5.
A feedback system has a dominant pole at -2 and another at -10. If the feedback increases the dominant pole to -1.5, analyze the effects on system stability.
Show hintHide hint
Consider the implications of closer proximity to the axis.
Question 6.
Given a Bode plot that shows a steep drop after a certain frequency, deduce the potential pole configuration for the system.
Show hintHide hint
Reflect on how different pole types affect frequency responses.
