hi
i was studying the "wave characteristics of transmission lines". while considering the lines with resistive termination, the term "voltage reflection coefficient(VRC)" came.
With reference to the book, "Field and Wave Electromagnetics", by David K. Cheng,
the following expression was given for the VRC:
[tex]
\Gamma = \frac{Z_L - Z_0}{Z_L + Z_0} = |\Gamma|e^{j\theta_\Gamma}
[/tex]
[tex]
Z_0\text{ is the characteristic impedance, and } Z_L\text{ is the load impedance.}
[/tex]
This was when, the distance on the line was measured from the load towards the source.
I wanted to know whether the same formula holds if we measure the distance from source towards the load. I was trying to find the same and would still be trying out, but thought it would be good to know more... (you always get to know more than what you want at PF)
regards,
