Q177

For continuous-time system, state variable representation is d dt q(t) = Aq(t) + bx(t) What is the corresponding representation for discrete-time system?

For continuous-time system, state variable representation is q(t) = Aq(t) + bx(t)
What is the corresponding representation for discrete-time system?
A.
q[n] = Aq[n] + bx[n]
B.
q[n + 1] = Aq[n] + bx[n]
Answer
C.
q[n] = Aq[n - 1] + bx[n]
D.
[q(n + 1)] = Aq[n - 1] + bx[n - 1]
