 Post subject: Smith Chart Help
Posted: Fri Jan 06, 2006 5:58 pm 

I am self studying transmission lines and I have a question on smith chart. Consider the case when you're given reflection coefficient (tau_r), Z_not, and impedence (Z_r). You want to find reflection coefficient at any distance on transmission line, i.e., tau_d, and Z_d. I'm using
Tau(d) = (1 + Z_d)/(1 - Z_d) to find Z(d) but I don't get angle/phase correct this way. I don't understand where I am making a mistake and I would request some help on this.
