Welcome to Lecture 33 of the course "Digital Signal Processing" by Prof.David Koilpllai
Full Course: https://study.iitm.ac.in/es/course_pages/EE3101.html

Video Overview
This lecture provides a clear and practical exploration of the sampling process in the frequency domain. You will learn how continuous time signals are converted into discrete time signals and how this process replicates the signal's spectrum across frequencies. We will explain the Nyquist Shannon sampling theorem and why it is essential to prevent aliasing during sampling. The session also covers how ideal reconstruction filters can recover the original signal and what happens when the sampling conditions are not satisfied. This foundational understanding will strengthen your ability to analyze and process signals in both the time and frequency domains in digital signal processing.
