Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a complex two-port network with Z_22 = 100Ω, Z_11 = 50Ω, Z_S = 25Ω, Z_{12} = 30Ω, and Z_{21} = 30Ω, calculate Z_out.

💡 Hint: Carefully plug in values using the formula for Z_out.

Challenge 2 Hard

Discuss the consequences of an impedance mismatch in a two-port network when Z_out is very high compared to the load.

💡 Hint: Think about how devices interact when their impedances are different.
