Welcome to Lecture 12 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 concept of discrete time systems which transform input sequences into output sequences in signal processing. We will begin by exploring the memoryless property with examples such as scaling quantization and rectification and then move to systems with memory including averaging examples to illustrate causal and non causal behavior. The lecture then covers linear systems emphasizing the principle of superposition which includes scaling also called homogeneity and additivity. You will also learn about time invariance and understand why combining linearity and time invariance is important for analyzing and designing systems. These core properties will help you build a strong foundation for studying discrete time signal processing and systems analysis.
