• Multi-input multi-output (MIMO) system
• sampled-data system
• zeros

This note analyzes the zeros of the sampled-data models corresponding to continuous-time decouplable MIMO systems with all relative degrees less than or equal to two and shows approximate expressions of the zeros as power series expansions with respect to a sampling period. Further, stability criteria of the zeros for small sampling periods are given.
