yeah, that's exactly what I'm thinking of! I've never seen it by this name!
What does the Z-transform get used for in the signal processing world?

@hallasurvivor you use it to design filters and assess their properties by looking at the poles of their Z-transform. For example, conventions are usually set such that a causal filter is "stable" (does not produce infinite output from finite input) if none of its poles lie in in the unit disk. You can look up linear time-invariant systems for more informations.
