Everything Students Should Know About Convolution of Discrete Signals
Convolution is a way to combine two signals to form a third signal. So, convolution of discrete signals simply means combining two discrete signals to form a third signal. In this post, we’ll give you a stepbystep guide on how to perform convolution by graphical method. We’ll also share some reallife examples of discrete signal…

Introduction to Signals & Systems
We studied about the basics of signals and systems in this previous post: Signals and Systems Basics In this post, we’ll dive deeper into the definition of a signal and the definition of a system – along with each one’s types. What are signals and its types? Signals are functions of one or more independent…
