| Jan 12, 2020 at 17:48 | comment | added | Matt L. | @themagiciant95: The one that is relevant for linear time-invariant systems: BIBO-stability. A continuous-time system with all its poles in the left-half plane could transform to a discrete-time system with poles outside the unit circle of the z-plane. | |
