The scattering parameter expression of twoport properties of impedance Z (in series connection) and admittance Y (in parallel connection) are discussed and their active RC model is presented.
讨论了用散射参数表达的串联阻抗Z和并联导纳Y的二端口特性，给出了它们的有源RC电路模型。

Two PC can communicate to each other by COM port and you can change the serial port parameter with the program.
程序可以实现利用 PC机的两个 COM口实现异步通信，并能根据设置调整异步传行通信 参数。

The common measurement of the two-port network'input impedance is to measure the S parameter, then Z parameter is calculated by the relation of S and Z, finally the input impedance is gained by the Z.
