Ok, I'm still stumped here. Can someone please show me a reference to
how the bi-linear transform is created without using trapezoidal
integration?
not that you wanna hear from me, but the usual "derivation" in textbooks
goes something like this:
z = e^(sT)
= e^(sT/2) / e^(-sT/2)
=approx (1 + sT/2)/(1 - sT/2) (hence the "bilinear"
approximation)
solving for s gets
s =approx 2/T * (z-1)/(z+1)
