Example 9.16 (a).  Use z-transform methods to solve     with  .  

Explore Solution 9.16(a).

It is worthwhile to point out how Mathematica can do the important step using residues.

    To solve     with  ,  we will use our Mathematica subroutine    for finding the solution to  .   It will take the z-transforms of each term;  solve for  ;  and it's inverse .   The format of the subroutine call is     with   .
