About this document

Discrete Time Fourier Transform Overview by J Jesús Villanueva García is a document available to read on EtoBox.

This document discusses various transforms used in digital image processing, including the discrete time Fourier transform (DTFT), discrete space Fourier transform (DSFT), and 2-D Z-transform. It provides definitions and properties of these transforms, such as the DTFT being periodic with period 2π and the DSFT being a 2-D periodic function. It also describes relationships between the transforms, such as the DTFT being the 1-D Z-transform evaluated on the unit circle and the DSFT being the 2-D Z-transform e
