thanks..
One requirement in my subject wire communication is to make a program of a smith chart. The output that our instructor want is the plotting of points on the chart. For example your given input the value of Zo and Zt, and then your required to solve for the reclection coefficient, VSWR, length of the stub matching, and etc., you can solve this mathematically but what our instructor want is to plot the output directly on the smith chart.
Thanks kinjal...I really appreciate your effort to help. Thanks andGod Bless!
