Which one most appropriate dynamic system?
y(n) + y(n - 1) + y(n + 1)
y(n) + y(n - 1)
y(n) = x(n)
y(n) + y(n - 1) + y(n + 3) = 0
Answer: Option
Explanation:

Because present output of y(n) depend upon past y(n - 1) and future y(n + 1).

Sir system output does not depends on depends on future I think there is no correct answer.

Sir, in this question objects are wrong please creation y(n) = y(n-1)+y(n+1).

Yes @Mr. Khalique is absolutely correct.

Because the system equation must represent some response. So in option D, the response is given but not in A.

Khalique said:   1 decade ago
Only option D represents system option A does not represent any system. Hence D must be the correct choice.
