Z Transform
I.
The Z transform is an adaptation of the Laplace transform for the study of:
continuous systems
discrete systems
random systems
II.
A discrete system of which the transfer function is expressed as a function of Z is stable if all the pole modules are:
equal to 1
less than 1
greater than 1
III.
The Z transform of the Dirac impulse is:
1
1/z
1/z²
