Signals and Systems

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).

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

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

Joshi said: 7 years ago

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

Apurva said: 8 years ago

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

Chiku said: 8 years ago

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

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

Mohit said: 8 years ago

The Dynamic system depends on present and past i/p o/p. So option b is correct.

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

Sridevi said: 8 years ago

Please, tell me the correct answer with the explanation.

Rangu said: 8 years ago

Dynamic system depends on past Input and past output.
