Two lossy lines are to be joined end to end. The first line is 10 m long and has a loss rating of 0.20 dB/m. The second lines is 15 m long and has a loss rating of 0.10 dB/m. The reflection coefficient at the junction (line 1 to line 2) is Γ = 0.30. The input power (to line 1) is 100 mW. Determine the total loss of the combination in dB to the output end of line 2.
