Sorry, the one above is wrong, of course. Given the minus-signs in the original transfer formula it should be:
zb = (fb1 +- sqrt(fb1*fb1 + 4*fb2)) / 2
if I'm right.
see, Chuck, if Frank gets it wrong what chance do i have? ;-)
;)
Attached is a patch which shows one of my failed attempts to try something to get a real/imaginary pair out of the formulas I derived. It's completely wrong, but might illustrate our problems.
