Thoughts, comments.

Peter, I for one, have missed your style.

Consider the following:

I(s)
+--------------------------------------------open
|
V(s) 1/4 wavelength, Z0=600 ohms
|
+--------------------------------------------open

Given: The ratio of V(s)/I(s) is 50+j0 ohms. Can you
solve for f(Z0)?
