Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a two-port network with S-parameters S_{11} = 0.25, S_{22} = 0.35, S_{12} = 0.6, S_{21} = 0.8, evaluate the Rollett Stability Factor K and determine stability.

💡 Hint: Break down the calculations step by step to determine K.

Challenge 2 Hard

Design a scenario where you must adjust a feedback loop in a system to avoid RHP poles. What adjustments would you consider?

💡 Hint: Think about fundamental feedback control principles.
