Challenge Problems
Push your limits with challenges.
Question 1
Consider a two-port network with S-parameters: S11 = 0.3, S22 = 0.25, S12 = 0.5, and S21 = 0.6. Determine K and analyze if the network is stable. Discuss the significance of the resulting K value in the context of feedback systems.
💡 Hint: Remember to follow the calculation steps carefully and consider the implications for the design.
Question 2
A network has S11 = 0.1, S22 = 0.1, S12 = 0.4, and S21 = 0.9. Calculate K and determine if changes are needed for stability when used in an amplifier design.
💡 Hint: Analyze each parameter carefully and think of the practical applications.
