SLP state representation and transmittance
Temporal analysis - Part 1

We have seen that under the action of a load u (t, t ₀ ) (cf. equation (1) ), a system undergoes a change in its state x (t, t ₀ ) via an evolution function f, and produces a response y (t, t ₀ ) given by the output function g. In the case of a linear system, the functions f and g are linear:
