Signals And Systems Lab

Block No.4, Room No. 423, ECE Dept, MAIT

The purpose of this LAB is to reconcile the declarative (what is) and imperative (how to) points of view on signals and systems. The mathematical treatment that dominates in the associated text is declarative in that it asserts properties of signals and studies the relationships between signals that are implied by systems. This laboratory manual focuses on an imperative style, where signals and systems are constructed procedural.

Through-out this lab we will be using MATLAB for the simulation of signals and systems. MATLAB is a very powerful vector/matrix oriented programming language.

The lab is divided into two distinct sections, in-lab and independent. The purpose of the in-lab section is to introduce concepts needed for later parts of the lab. Each in-lab section is designed to be completed during a scheduled lab time with an instructor present to clear up any confusing or unclear concepts. The in-lab section is completed by obtaining the signature of an instructor on a verification sheet.

The independent section begins where the in-lab section leaves off. It can be completed within a scheduled lab period, or may be completed independently. Students should write a brief summary of their solutions to the lab exercise. The summary should clearly answer each question posed in the independent section of the lab. The lab writeup should be kept simple. It will typically include the names of the members of the group (if the lab is done by a group), the time of the lab section, the name of the lab, and the date. It should then proceed to give clear answers to each of the questions posed by the lab. MATLAB code should be provided in a fixed-width font and plots should be clearly labeled and referenced in the writeup. Plots may be included directly in the flow of the analysis. If included on a separate page, two to eight plots should be placed on the same page, depending on the nature of the plots. Students can copy MATLAB plots into most word processors using the Copy Figure command in the Edit menu.

The laboratory will focus on the use of MATLAB to explore signals and systems. The text for this lab includes a collection of MATLAB functions specialized for the signal processing taught in signals and system.
