which of the following statements are true?
a system is said to be finite impulse responses,if the output samples of the system depend only on the present input and a finite number of past or previous input samples.
if the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a non recursive system.
if the output of a system y(n) depends only on the present input and past inputs, but not on past outputs ,then it is called a recursive system.
a system is always a recursive one.
