3: A 50-MHz generator with Zg =50Q is connected to a load ZL= (50 -j 25). The time average power transferred from the generator into the load is max when Zg=Z₁L, where Z₁ is the complex conjugate of ZL. To achieve this condition without changing Zg, the effective load impedance can be modified by adding an open circuited line in series with ZL, as shown in the following figure. If the line's Zo=10002, determine the shortest length of line (in wavelengths) necessary for satisfying the maximum power transfer condition. Zo 100 2- 50 Ω Z₁ (50-125) 4: Repeat Problem 4 for a short circuit line in series with ZL.
