Which of the following gives the complete definition of the state of a system at time n0?
A. Amount of information at n0 determines output signal for n≥n0
B. Input signal x(n) for n≥n0 determines output signal for n≥n0
C. Input signal x(n) for n≥0 determines output signal for n≥n0
D. Amount of information at n0+input signal x(n) for n≥n0 determines output signal for n≥n0
Answer:A
Which of the following gives the complete definition of the state of a system at time n0?
A. Amount of information at n0 determines output signal for n≥n0 B. Input signal x(n) for n≥n0 determines output signal for n≥n0 C. Input signal x(n) for n≥0 determines output signal for n≥n0 D. Amount of information at n0+input signal x(n) for n≥n0 determines output signal for n≥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.
