The special case of a finite-duration sequence is given as
\(x\left( n \right) = \left\{ { 2,\begin{array}{*{20}{c}} 4\\ \uparrow \end{array},0,3} \right\}\)
The sequence x(n) into a sum of weighted impulse sequences will be
1
2δ(n + 1) + 4δ(n) + 3δ(n – 2)
2
2δ(n) + 4δ(n –1) + 3δ(n – 3)
3
2δ(n) + 4δ(n –1) + 3δ(n – 2)
4
2δ(n + 1) + 4δ(n) + 3δ(n – 1)
