Modified z Transforms of Common Functions

We need to derive the modified z transformation of a few simple functions. 

Using the definition of the modified z transformation given in Eq. (18.127) gives 

Note that this modified z transform does not depend on the variable m since the function is constant in between the sample periods. 

Notice that this modified z transformation is a function of both m and z. 

EXPONENTIAL. As with all the transforms, this is the most important function.
