Which one most appropriate dynamic system?
Answer: Option
Explanation:
Because present output of y(n) depend upon past y(n - 1) and future y(n + 1).

Both A and D is correct. But in above question there is a statement given that "one most appropriate". Now option "a" is more appropriate bcoz y(n) + y(n - 1) + y(n + 1) bcoz this dynamic system contains value of +-1 at the same time. If option "D" is given like y(n) + y(n - 3) + y(n + 3) then there is confusion between A and D. But here there is no confusion.

An appropriate dynamic system is also a memory system. the output is dependent on past and future values. option A does not depend on anything because it has no output. So, we can express it as y(n) = y(n-1) + y(n+1) for it to become an appropriate system.

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.

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.

Options A and D both are correct.
The dynamic system means having a memory which is represented by past and future o/p
At given present i/p.

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

Option A and D is correct because both past and future value depends, and the option A has more correct than D due to order.

Dynamic system depends upon the past and future input and outputs. So in my view, option A and D are the correct answers.

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.

Only option D represents system option A does not represent any system. Hence D must be the correct choice.
