Yes, they're are LTI and as such, can be expressed as product sum of poles
and zeros and are convertible among each other. And regardless of s,z, or
y, they all hold the same information about the network/interconnect, just
under different conditions and perspectives or basis(plural). Now, that's
not to say that they're all just as easily usable under all circumstances
for time domain computations, depending on setup. This is just another
reason why proper setup (fmin-fmaz,deltaf) is important. Bottom line, it
all depends on what info youre trying to obtain.

Hi experts,
As we know when we need to use sparameter in time domain simulation, we
usually convert a sparameter into a rational model, or other circuit
approximation models. But can we convert the sparamter into zparameter or
yparameter for the same purpose? Theoretically, this seems doable to me.
But we may need the simulators to support running transient sim with Z, Y?
Best Regards,
Tramp
