I remember we had a book fair every year in grade school. I would get so excited when I saw all the science books with thrilling projects I could master. The goal of this book is to bring that experience to high school and college-level students. This book is full of projects that would be perfect for any high school level science fair up to university level senior design class. It can teach you how to create signals that can bewitch the mind, tame ferocious dogs, fight off insomnia, and destroy the human body. You will learn how to clean up noise from pre-existing signals, set up eyes and ears in places you are not, write apps that can monitor heart rate, or separate the colors of an object and so much more. All the projects are broken down and written in a way anyone could comprehend. All of these projects fall under the umbrella of DSP.
Digital Signal Processing (DSP) is the production of a new signal or the analysis of an existing one. There are various types of signals, such as audio, image, and electromagnetic. Sensors use either current or voltage to provide output information on the phenomenon they are monitoring. For example, in a Wii remote accelerometer, the phenomenon is the movement of the Wii remote by the gamer. Another example is how we use electromagnetic waves in cell phones for communication.
Síma (Σήμα Greek word for signal) is an application-based book, meaning these are programs you can write, test, and play with: not just learning the DSP theory.
This book assumes you are knowledgeable on using Microsoft Visual Studios, C #, and object-oriented programming.
