Determine the inverse z-transform of $F(z)=\frac{z}{z^{2}-3 z+2}$ Since $\mathrm{F}(\mathrm{z})=\frac{z}{z^{2}-3 z+2}$ then $\frac{F(z)}{z}=\frac{1}{z^{2}-3 z+2}$ Using partial fractions, let $$ \begin{aligned} \frac{1}{z^{2}-3 z+2}=\frac{1}{(z-1)(z-2)} &=\frac{A}{(z-1)}+\frac{B}{(z-2)} \\ &=\frac{A(z-2)+B(z-1)}{(z-1)(z-2)} \end{aligned} $$ from which, $1=\mathrm{A}(\mathrm{z}-2)+\mathrm{B}(\mathrm{z}-1)$ Letting $z=1$ gives: $1=-A$ i.e. $A=-1$ Letting $z=2$ gives: $1=B$ Hence, $$ \frac{F(z)}{z}=\frac{-1}{(z-1)}+\frac{1}{(z-2)}=\frac{1}{(z-2)}-\frac{1}{(z-1)} $$ and $\quad F(z)=\frac{z}{(z-2)}-\frac{z}{(z-1)}$ Thus, $$ \begin{aligned} Z^{-1} \mathrm{~F}(\mathrm{z}) &=Z^{-1}\left\{\frac{z}{(z-2)}-\frac{z}{(z-1)}\right\} \\ &=Z^{-1}\left\{\frac{z}{(z-2)}\right\}-Z^{-1}\left\{\frac{z}{(z-1)}\right\} \end{aligned} $$ From 6 in Table 79.1, $\boldsymbol{Z}^{-1} \mathbf{F}(\mathbf{z})=(2)^{k}-(1)^{k}=(\mathbf{2})^{k}-\mathbf{1}$
