5 Arrays of LTI Models

The Concept of an LTI Array
To visualize the concept of an LTI array, consider the set of five transfer
function models shown below. In this example, each model has two inputs and
two outputs. They differ by parameter variations in the individual model
components.

Each element of the LTI array
is a model.
This LTI array embodies a
1-by-5 list of models.
