Talk:Impedance parameters

'''History of Impedance Parameters ''' I'd like to see some content about the historical development, and motivation behind their development, of impedance parameters, and also of the other various n-port parameters: S, Y, Z, H, T, etc, on their respective pages.

Scattering matrix
The expression for the scattering matrix given here is only true when the characteristic impedances are all real. In general, I believe it should be $$S = F\cdot(Z-z^\ast) \cdot (Z+z)^{-1} \cdot F^{-1}$$, where $$F=\left(2\sqrt{\Re[z]}\right)^{-1}$$. Enthree (talk) 03:51, 27 August 2020 (UTC)
