Description

The code is a LaTeX document that uses the packages circuitikz and tikz. It draws a schematic diagram of a transmission line network with a signal generator connected to an input impedance Z_g via a two-port block. The network also includes two transmission lines of equal length connected in parallel between Z_g and Z_L, and a load impedance Z_L connected to the output via another two-port block. The style of the block is defined by a tikzstyle command. The final line connects the input of the network to ground using a sI element.

Keywords
