hi guys.(adsbygoogle = window.adsbygoogle || []).push({});

Just want to clarify something with the z transform and convergence.

Do you guys aggree with this.

If an expression does not converge you CAN STILL find the z transform (using power series) for the system HOWEVER this will not be the closed form z transform.

just wondering - because in any z transform table you are given a region of convergence - but this is for closed form z transforms.

I suppose all systems are stable if they converge.

thanks
