Z Transform

I. The Z transform is an adaptation of the Laplace transform for the study of:

  1. continuous systems
  2. discrete systems
  3. 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:

  1. equal to 1
  2. less than 1
  3. greater than 1


III. The Z transform of the Dirac impulse is:

  1. 1
  2. 1/z
  3. 1/z²
