You are designing a circuit with an input signal of 10V and a current of 2A flowing into the input. Calculate Z_in. How would you proceed?
💡 Hint: Use the fundamental definition of input impedance.
In a circuit with Z_{12} = 0.5Ω, Z_{21} = 1Ω, Z_{22} = 2Ω, and Z_L = 3Ω, compute Z_in if Z_{11} = 4Ω.
💡 Hint: Follow the Z_in formula step-by-step for clarity.
