For a casual LTI system the impulse response is \(h(n)= \left\{ {\mathop 1\limits_ \uparrow ,2,1,3} \right\}\). What will be the system difference equation?
1
y(n) = x(n) - 2y(n - 1) - y(n - 2) - 3y(n - 3)
2
y(n) = x(n) + 2x(n - 1) + x(n - 2) + 3x(n - 3)
3
y(n) = x(n) - 2x(n - 1) -x(n - 2) - 3x(n - 3)
4
y(n) = x(n) + 2y(n - 1) + y(n - 2) + 3y(n - 3)
