Challenge Problems
Push your limits with advanced challenges
Consider a two-port network with Z_{11} = 50Ω, Z_{12} = 10Ω, Z_{21} = 10Ω, Z_{22} = 40Ω, and Z_L = 60Ω. Calculate Z_in and explain how changes in Z_L might affect the entire network.
💡 Hint: Follow through the impedance formulas provided.
If Z_{22} = 80Ω, Z_S = 20Ω, Z_{11} = 90Ω, and Z_{12} = Z_{21} = 5Ω, determine Z_out and discuss its relevance to signal integrity in circuits.
