Challenge Problems
Push your limits with challenges.
Question 1
Given a complex two-port network with Z_22 = 100Ξ©, Z_11 = 50Ξ©, Z_S = 25Ξ©, Z_{12} = 30Ξ©, and Z_{21} = 30Ξ©, calculate Z_out.
π‘ Hint: Carefully plug in values using the formula for Z_out.
Question 2
Discuss the consequences of an impedance mismatch in a two-port network when Z_out is very high compared to the load.
π‘ Hint: Think about how devices interact when their impedances are different.
