Signals on ℤ(T)

  • Gianfranco Cariolaro


Discrete-time signals were introduced in Chap.  2 and studied in a preliminary form, following a classical approach. In this chapter they are reconsidered as signals defined on ℤ(T) following the UST. Relevant concepts that are specific to this class of signals, in particular the z-transform and the discrete Hilbert transform, are introduced.

Nowadays discrete-time signals represent the most important class because they can be manipulated with the powerful techniques and tools of digital signal processing and multirate systems.
