Question 1
In a feedback system with A = 250 and Ξ² = 0.05, calculate the new voltage gain if the input signal is 200 mV and derive the final output voltage.
π‘ Hint: Make sure to start from calculating the voltage gain first!
Question 2
Discuss how altering Ξ² from 0.05 to 0.1 impacts the new output voltage and input/output resistances. Assume A remains constant.
π‘ Hint: Reference how we calculated resistances related to feedback factors.
