Lecture

Discrete-Time Fourier Transform

Description

This lecture covers the definition and properties of the discrete-time Fourier transform (DTFT), including the inverse transform and its application to LTI systems. The instructor explains when the DTFT is well defined and provides examples such as the rectangular pulse and the unit impulse. Additionally, the lecture discusses DTFT pairs, constant signals, harmonics, step functions, and other signal transformations.
