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?
Explanation: 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.

Which of the following gives the complete definition of the state of a system at time n0?
Explanation: We define the state of a system at time n0 as the amount of information that must be provided at time n0, which, together with the input signal x(n) for n≥n0 determines output signal for n≥n0.

Pass Ratio : 100%
A single input-single output system and its transpose have identical impulse responses and hence the same input-output relationship.
Explanation: If h(n) is the impulse response of the single input-single output system, and h1(n) is the impulse response of the transposed system, then we know that h(n)=h1>(n). Thus, a single input-single output system and its transpose have identical impulse responses and hence the same input-output relationship.
