CONCLUSIONThrough the experiment, I have understood the concept of two-port network and able to set up atwo-port circuit and perform the calculation of parameters using the measured voltages andcurrents values and compared it with the theoretical results. Furthermore, I also understood that itis inevitable to has slight difference in values between the experimental results and theoreticalresults due to the errors occurred during the experiment process and calculation, for examplesystematic error caused by the environment and instrument, gross error caused by the human andrandom error which is the combination of many errors. Thus, it is important for us to select thesuitable apparatus and methods for the experiment and be careful and patient when undergoingthe experiment and calculations so that the errors will be minimize. However, it is not necessaryfor the experimental results to be perfect matched to the theoretical results because it isimpossible, as long the experimental results are in tolerance range, the results are considered asaccurate.REFERENCES1.Christopher K.

For thecalculation of Z21and Z11, simply repeat the steps used in the previous calculation by open theoutput port(port 22’) and I2become 0A. The calculations of z-parameters are simplfy and shownin below.V1= Z11I1+ Z12I2V2 = Z21I1+ Z22I2Formula and method used to calculate y-parameter:For the calculation of y-parameter, first we should short the input port (port11’), which will resultin the value of V1becomes 0V and allows us to calculate the values of Z by finding the effectivevoltage and current values from the given resistors values. For the calculation of Z21and Z11,simply repeat the steps used in the previous calculation by open the output port(port 22’) and V2become 0V. However, be noted that as the port been shorted, the current will choose to flowthrough the short circuit part and some resistors have to be neglected in the calculation. The
