Solution
ОглавлениеThe output port is open‐circuited, I2 = 0. Therefore, equation (3.1.17) provides V1 = A V2 and I1 = CV2. For the port 2 of Fig (3.6) open‐circuited, I2 = 0, V1 = V2 and I2 = I1 = 0. On comparing these equations, the computed parameters are A = 1 and C = 0.
For the output port is short‐circuited, V2 = 0. Therefore, equation (3.1.17) helps to get, V1 = BI2 and I1 = DI2. Using Fig (3.6) shows, V2 = 0, V1 = ZI2 and I1 = I2. The comparison of these equations provide B = Z and D = 1.
Thus, the [ABCD] matrix of series impedance is written as
