A. The one just posted by Peter, (Zl - Z0conj) / (Zl + Z0conj)

B. Slick's, (Zl - Z0conj) / (Zl + Z0)

This is the correct formula.

it is??? -10 points and repeat last week's homework.


Who are you to correct my homework? Look it up yourself

It's absolutely the correct formula

For passive circuits, 0=[rho]=1,

And strictly speaking: Reflection Coefficient =
(Zl-Zo*)/(Zl+Zo)

Where * indicates conjugate.



C. The one in all my texts and used by practicing engineers, (Zl - Z0) /
(Zl + Z0)



This formula is correct too, but only because most texts assume a
purely real Zo.

F+, and take the whole class again.
