Challenge Problems
Push your limits with advanced challenges
An amplifier has Z_{11} = 50Ω, Z_{12} = 25Ω, Z_{21} = 25Ω, Z_{22} = 75Ω, and Z_L = 100Ω. Calculate the input impedance Z_{in}.
💡 Hint: Use the input impedance formula carefully and substitute the terms.
If an amplifier's output impedance is Z_{out} = 30Ω, and it is coupled with a load resistor of 15Ω, discuss the impact on the output signal.
💡 Hint: Consider how output impedance affects load interactions.
