SIGNAL & SYSTEM LABORATORY

The Signals and Systems is concerned with the representation of signals and the study of the changes that occur to them as they pass through systems. It provides a foundation for the Signal Processing, Control, and Communications Engineering modules covered later in the undergraduate curriculum. The study of Signals and Systems is to allow one to predict, with some certainty, the behavior of systems when they are subjected to different input signals. The area of Signal system has advanced rapidly over the last four decades. This advancement is attributed to the progress in digital computer technology and integrated circuit fabrications.

Objectives:

In this course, the student will acquire hands-on experience with programming in MATLAB. MATLAB will enable you to study and understand the theory behind signals and systems as well as validate the theory with real-world examples. The labs will cover linear time-invariant systems, Fourier series and Fourier transform, sampling, digital filters, along with several accompanying digital signal-processing (DSP) applications.
