What is the difference between dft and z transform

What are the basic defferences between z-transform and DTFT. Thread starter rizwanspirit Start date Nov 20, Status Not open for further replies. The applications of the two transforms, however, are quite different. Another difference is that the analysis of the Z transform is valid for all types of signal periodic, increasing, decreasing, etc , but the DTFT its valid only for signal that has finite energy and the completely periodic signals.

The difference is that ZT is more general version. Z can be any complex. Similar threads S. Elementary Electronic Questions. What is the basic difference between microprocessor and microcontroller?

Yes I agree that Z transform is the digital equivalent of laplace transform. I have written the sentence above which is taken from the signal processing book.

I just want the illustration of this. I think you can now understand what I am trying to say. I just need the interpretation. Show 7 more comments. Sign up or log in Sign up using Google.
