Welcome to Lecture 9 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 you will learn the fundamental properties and classifications of discrete time signals essential for your understanding of signal processing. We will define and differentiate between finite length and infinite length sequences and explain the concepts of causal anti causal right sided and left sided signals with clear examples. These classifications are important for analyzing and designing discrete time systems in engineering. The lecture concludes with a discussion on the properties of discrete time sinusoids to prepare you for advanced signal analysis.
