Hi,
I learn Smith chart from this tutorial, but I find its description is different from its figure.
First of all, I cannot get the normalized impedance (0.5, 18 degree). At least the angle should be a negative value.

z_L = 2.5 – j1 = 0.5/18°


Could you help me on the understanding?


Thanks,

Sorry, I am confused now with 0.5/18°. What does 0.5/18° mean in below? How is it obtained? Can I calculate it from 2.5-j1?

If it is zL's reflection coefficient, the angle should be -18°. Am I right?


point L represents a normalized load
impedance z L = 2.5 – j1 = 0.5/18°



Thanks,

Could you tell me where I can learn this equation?

Hello,

I read below equation on a slide. I am new to this topic and would like to learn about it. Could you tell me the name and what tutorial could talk about it on line?

Thanks,

Excuse me. I know now it is about transmission line. A new question is here. What is 'v' in below picture (I put a red line below ''v"). I don't find an explanation about it on the slide file. Could you explain it to me?
