A sequence x(n) with the z-transform X(z) = z4 + z2 – 2z + 2 – 3z-4 is applied as an input to a linear, time-invariant system with the impulse response h(n) = 2δ (n - 3) where
\(\delta \left( n \right) = \left\{ {\begin{array}{*{20}{c}} 1&{n = 0}\\ 0&{otherwise} \end{array}} \right.\)
The output at n = 4 is
