EEGR 221 MATLAB Project 1
Basic Signals and System properties
Fall 2016
Due date: 10/3/16
1. Review the MATLAB tutorials provided on Bb and plot the following signals.
Instructions: Plot this signal between t=[-5 to 10]. For each plot you must label x and y axis and
have a title for the plot. Following commands could be used. heaviside, plot, axis, ylabel, ylabel,
title, etc … At the command prompt of MATLAB you can type >> help [command name] to get help
with any command. plot all of the signal for t between -5 and 10 seconds.

2. Plot x4, x5, and x4+x5 on the same figure using different colors. Is x4+x5 periodic? If yes, what is
the period of x4+x5 signal in relation to the periods of x4 and x5? Clearly show the period on the
graph and state your analysis and explanation. Label all of the axis and signals using the
previous and other MATLAB commands such as “figure”, “hold on”, and “legend”.
3. The system y(t) = x 3(t) is not linear. Perform the scalability test manually and submit your
hand calculation. Also in MATLAB use x(4) as the input to this system to show that this system
is not linear. You can show all of the input and output signal and their scaled version and make
a strong argument based on the graphs that this system is not scalable, so not linear.
How to report the results?



Save your commands in an m-file with your name in the name field. (e.g. John_Scott.m) and
append the code to the end of your report.
Your report must be organized in three sections for systems: problem 1, 2, and 3.
In each part the problem should be clearly identified. Type the problem statement in each
section. Show the plots of input and output signals. Draw conclusions based on your plots and
in problem 3 discuss why the property is not satisfied based on your plots.
Submit soft copy of your report on Bb before the deadline. This report must include a cover page
with the name of both student partners.
