Basic Examples  (2)

A discrete-time system:

Wolfram Language code: DiscreteTimeModelQ[StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> τ, SystemsModelLabels -> None]]

Select discrete-time models:

Wolfram Language code: Cases[{StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> 1, SystemsModelLabels -> None], a, StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> τ, SystemsModelLabels -> None]}, _ ? DiscreteTimeModelQ]
