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).

Why option D can't be the answer?

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

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.

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

Nag. said:   10 years ago
Sir system output does not depends on depends on future I think there is no correct answer.

If option A is correct then option D also should be correct. Whoever the author of the question explain with correct answer.

Y Sarma said:   9 years ago
I think A and D both are correct.

If it's true then we have to choose A as an answer because of priority of order.

Harini said:   9 years ago
The dynamic system depends only on past outputs or past inputs and not on future outputs, Hence option A and D can't be correct and option C is a static system. So option B may be the right answer.

Please tell me which is the correct answer?

Rangu said:   8 years ago
Dynamic system depends on past Input and past output.
