Project-1

Total Points: 100, Due Date: 10-05-2018

Project Statement/Problem

Using MATLAB, create and plot the following signals for time 𝑡 = −10 to 𝑡 = 10.

a) 𝑥1(𝑡) = 𝑒 −0.2𝑡

b) 𝑥2(𝑡) = 1 − 𝑒 −0.2𝑡

c) 𝑥3(𝑡) = 𝑒 0.2𝑡

d) 𝑥4(𝑡) = 1 − 𝑒 0.2𝑡

e) 𝑥5(𝑡) = cos(0.5𝜋𝑡)

f) 𝑥6(𝑡) = 𝑒 −0.2𝑡 cos(0.5𝜋𝑡)

g) 𝑥7(𝑡) = 𝑒𝑗𝑡+𝑒−𝑗𝑡

h) 𝑥8(𝑡) = 𝑒𝑗𝑡−𝑒−𝑗𝑡

Other Instructions

• Create one single m-file and include the coding for all twelve signals in the same file. Save

your m-file as Project1_LastName_FirstName.m.

• Run the file to generate the outputs/plots. Remember to include ‘grid’, and appropriate/relevant

‘axes labels’ and ‘title’ in each plot.

• Put the complete code and the corresponding outputs (plots) in a Word document. Include

figure captions, as/if needed.

• Submit the printed/paper version of the word document (project report) with a cover page

• Email the m-file (actual MATLAB code) to the instructor within the deadline.

Warning

• Each student must do his/her own project.

• Any trace of copying/plagiarism (from others or from internet) will result in zero points/credit

in the project.

• If two or more projects (codes, report) can be identified as having traces of copying/plagiarism

from each other, all those project works/reports will get zero points/credit.
