Inverse Systems for LTI Systems Described by Difference Equations

z-transform analysis of inverse systems for linear constant-coefficient difference equations, including conditions for a stable and causal inverse system.

Thanks for the video, Barry! It is really helpful. Just a question on stability. All the poles has to be less than 1 for the system to be stable and causal. Does all the zeros has to be less than 1 too for a stable and causal system to exist?

No..Not necessary

[@trakmator]

only if you want to have a causal and stable inverse
