Question 1
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.
💡 Hint: Use the formula for the new pole location discussed in class.
Question 2
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.
💡 Hint: Keep in mind how feedback modifies both poles based on their interactions.
