Hãy xác định Y(Z)=ZT[y(n)]. Nếu ZT[x(n)=X(z) và y(n)=x(n-n0)

$\text{Y}\left(\text{Z}\right)=Z{}^{n{}_0}X\left(Z\right)$

$\text{Y}\left(\text{Z}\right)=Z{}^{-n{}_0}X\left(Z\right)$

$\text{Y}\left(\text{Z}\right)=n{}_0\cdot X\left(Z\right)$

$\text{Y}\left(\text{Z}\right)=[X\left(Z\right)]{}^{n{}_0}$
