8.Find scattering matrix of following network. Also comment about reciprocity and find whether lossless or not. where X1=50 and X2=100. Zc 9.Use SFG to find overall reflection coefficient at input and output. Take source and load impedance to be 50 92. 0 0 0.44-45. V N 0 ? 8.560 Zc = 50 52 10. A four-port network has the scattering matrix shown as follows. If ports 3 and 4 are connected with a lossless matched transmission line with an electrical length of 30, find the resulting insertion loss and phase delay between ports 1 and 2 (Use signal flow graphs).
