Challenge Problems
Push your limits with advanced challenges
In a feedback system with A = 250 and β = 0.05, calculate the new voltage gain if the input signal is 200 mV and derive the final output voltage.
💡 Hint: Make sure to start from calculating the voltage gain first!
Discuss how altering β from 0.05 to 0.1 impacts the new output voltage and input/output resistances. Assume A remains constant.
💡 Hint: Reference how we calculated resistances related to feedback factors.
