#table(
columns: 8,
align: (x, y) => if x == 7 {left} else {center},
stroke: none,
$6$,$5$,$4$,$3$,$2$,$1$,$0$,
table.vline(),
$n$,
table.hline(),
[],[],[],$-4$,$3$,$-2$,$1$,$v(n)$,
[],[],[],$-1$, [], $1$, $4$, $x(n)$,
table.hline(),
[],[],[],$-16$,$12$,$-8$,$4$, [],
[],[], $-4$, $3$, $-2$, $1$, [], [],
$4$, $-3$, $2$, $-1$, [],[],[], [],
table.hline(),
$4$, $-3$, $-2$, $-14$, $10$, $-7$, $4$, $w(n) = v(n) * x(n)$
)
