Project Statement/Problem

Using MATLAB, create and plot the following signals for time 𝑑 = βˆ’10 to 𝑑 = 10.

a) π‘₯1(𝑑) = 𝑒 βˆ’0.2𝑑

b) π‘₯2(𝑑) = 1 βˆ’ 𝑒 βˆ’0.2𝑑

c) π‘₯3(𝑑) = 𝑒 0.2𝑑

d) π‘₯4(𝑑) = 1 βˆ’ 𝑒 0.2𝑑

e) π‘₯5(𝑑) = cos(0.5πœ‹π‘‘)

f) π‘₯6(𝑑) = 𝑒 βˆ’0.2𝑑 cos(0.5πœ‹π‘‘)

g) π‘₯7(𝑑) = 𝑒𝑗𝑑+π‘’βˆ’π‘—π‘‘

Other Instructions

β€’ 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.

β€’ Run the file to generate the outputs/plots. Remember to include β€˜grid’, and appropriate/relevant

β€˜axes labels’ and β€˜title’ in each plot.

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

figure captions, as/if needed.

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

within the deadline.

β€’ Email the m-file (actual MATLAB code) to the instructor within the deadline.

Warning

β€’ Each student must do his/her own project.

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

in the project.

β€’ 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.
