Question 1
What is the expression for input impedance in a terminated network?
- Z_{in} = Z_{11} + (Z_{12}Z_{21} / (Z_{22} + Z_L))
- Z_{in} = Z_{11} - (Z_{12}Z_{21} / (Z_{22} + Z_L))
- Z_{in} = V_1 / I_2
π‘ Hint: Remember the roles of Z_{11}, Z_{12}, Z_{21}, and Z_{22}.
Question 2
True or False: Higher input impedance is always better for circuit performance.
- True
- False
π‘ Hint: Consider the relationship between source and load.

Question 1
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?
π‘ Hint: Use the fundamental definition of input impedance.
Question 2
In a circuit with Z_{12} = 0.5Ξ©, Z_{21} = 1Ξ©, Z_{22} = 2Ξ©, and Z_L = 3Ξ©, compute Z_in if Z_{11} = 4Ξ©.
π‘ Hint: Follow the Z_in formula step-by-step for clarity.
