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).

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.

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.

I think option B is correct.

Option A doesn't even show the equation of a system, hence option D is the more appropriate answer.

As option A does not have the proper form of expression, so D must be the correct option.

Option D is correct because A is not a system.

How system depends on future output? it is unrealizable and option B is correct.

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.

In Dynamic systems, output depends on present input as well as past or future inputs.

Option A& D both are correct because both system satisfied condition of dynamic.
