[billyray]

Homework Statement

A transmission line has the primary coefficients .

R=2Ω/m
L=8nH/m
G=0.5mS/m
C=0.23pF/m

Determine the lines secondary coefficients Z0, α and β at a frequency of 1GHz

The Attempt at a Solution

included. I think its just a case of filling into formula I have but not 100% sure.

hi
thanks gneil. i have looked at this and my answer seems the same as i have used the same formula. on the first line of the equation they divide 0.5 by 2 and get 2.4. i know they are using a 10 to the power to mover decimal but 0.5 devided by 2 is 0.25 or am i missing something?

No, you're not missing anything, that's a genuine error. The result is not affected by much, 0.050 rather than 0.052, which are arguably the same result considering the number of significant digits in the given values

thanks gneil i will move on to the next one then.
