EE205 Signal and System LAB

IMPORTANT

The files in this project should follow the following instructions.

The name of the file

1. We will create a LABx folder for each LAB Session.
2. Files need to be named as Problem_subquestion_others.m, like P1_5_a1.m, except the name of functions, and set the name of the photos with filename_photoname_out/photoindex.png like P_1_5_a1_out1.png

The part contained in the code

1. The code implementation of the problem
2. Plot: We need to add all the setings to the plot in the code so that we do not need to adjust the polt if we replot it.
3. Save: the plots by function saveas(gcf, "plots/P1_4_f_out2.png");, here we are running the program in root dictionary. After save the image, you can use close to close the windows
4. For convinence, each signal x should have a relative position notation nx, which can be used in plots.

Basci instructions about plots

1. title('text') for the title of the plots

Issues

Any problem encontered in the LAB should be pasted to the issues page.

About the lab report

Format

1. The introduction section should include what you will do in this LAB
2. You can copy from the introduction of the problem
3. Argument and Analysis should be included in the LAB report
4. All MATLAB codes should be included at the end of the file.

Content

In a single LAB we should perform following steps:

1. Construct (a) signal(s)
2. Emulate
3. Compare

All the steps should be implicted in the report

Experience

Introduction

Here is the lab session of course Signal and System (EE205) in Southern University of Science and Technology (Shenzhen). In the lab session, we will use MATLAB to explore the properties of different signals.

Team members

• YUAN Tong (Student ID: 11810818)
• DAI Yujin (Student ID: 11910114)

Lab 1: MATLAB Programming

NOTICE: LAB1 should be submitted before 11th March

In lab 1

Proofing of linear system

We use unit pulse $\delta [n]$ as the test input, the system should satisfy:

1. 齐次性
2. 叠加性

Proofing of casualty

The out won''t depended on the input from future, to proof this we need to:

1. construct a step signal

Proofing the stability

输入有界，输出有界

when n=0 y=-Inf, the system is not stable.

Proofing inveribility

1 y only have one x to obtain it.

Lab 2: Linear Time-Invariant Systems

Lab 3: Fourier Series Representation of Periodic Signals

Lab 4: The Continuous-Time Fourier Transform

Lab 5: System, Transform, Convolution and Filter

And also there will we two projects to help studets apply all the technocs learned. The two projects will be held in another respositories

• Project 1. Speech synthesis and perception with envelope cue
• Project 2: OFDM Technology
