Welcome to Lecture 48 of the course "Digital Signal Processing" by Prof.David Koilpllai
Full Course: https://study.iitm.ac.in/es/course_pages/EE3101.html

Video Overview
In this lecture, we explore essential properties of the Discrete-Time Fourier Transform (DTFT) through practical problem-solving. You’ll learn how to compute the energy of signals using Parseval’s theorem, apply the frequency shifting and differentiation properties, and understand how known Fourier pairs can simplify complex analysis. We also cover the convolution theorem and demonstrate how these tools are used in real signal processing tasks. This session strengthens your foundation in DTFT, system analysis, and core DSP concepts.
