Question

The state space or the internal description of the system still involves a relationship between the input and output signals, what are the additional set of variables it also involves?

(a) System variables

(b) Location variables

(c) State variables

(d) None of the mentioned

I have been asked this question in my homework.

My query is from State-Space System Analysis and Structures topic in portion Discrete Time Systems Implementation of Digital Signal Processing

Answer 1

The correct choice is (c) State variables

For explanation I would say: Although the state space or the internal description of the system still involves a relationship between the input and output signals, it also involves an additional set of variables, called State variables.
