2.1 z-Transforms and Inverse z-Transforms
Indeed, the z-transform of a sequence is the generating function of this sequence, where the independent variable z is replaced by its reciprocal 1/ z. The z-transformation or z-transform today is applied to model sample-data control systems or other discrete-data systems.

In discrete time systems the unit impulse is defined somewhat differently than in continuous time systems. The Z Transform is given by. From the definition of the impulse, every term of the summation is zero except when k=0. So. Note that this is the same as the Laplace Transform of a unit impulse in continuous time.
