Answer 2

Answer:

Explanation:

Example: Z Transform of Finite Sequence

As a simple example, consider the sequence of sampled numbers, x[k]

For this sequence, the Z Transform of x[k] is given by:

This may seem a complicated way to define sequences, but it turns out that many sequences of interest to us (impulse, unit step, ...) will have Z Transforms that can be expressed in a compact form.
