ECE-2025 Lab Assignments
Spring-2004
The labs are posted in Adobe’s PDF format. You may
obtain a copy of the Adobe Acrobat Reader for
free from http://www.adobe.com.
Special instructions are noted on each assignment.
In general, Lab reports are due one week after doing the supervised warm-up.
Lab reports are due at the beginning of lab;
Labs turned in later on the same day will lose 5 points.
Please get the SP-First Toolbox M-files from
this link.
Un-zip and put these files at the BEGINNING of your MATLAB path.
Labs
| Description | Lab Dates | FAQ** | Supporting Material & Links |
| Lab #1 Intro to MATLAB | 12-15 Jan 04 | FAQ | Getting Started with MATLAB (2.6 Megabyte PDF file from Mathworks) Little Bits of MATLAB (Old MATLAB tutorial) Another MATLAB Tutorial (written by Prof. Heck of ECE) |
| Lab #2 Complex Exponentials | 20-26 Jan 04 | FAQ | This lab requires two supporting files: Lab02data.zip which contains some test data in the MAT file Lab02data.mat, and sensordatagen.zip which is a ZIP file containing sensordatagen.p, the p-code for generating amplitude and phase data at the sensors from a sinusoidal source. Tutorial movie about MATLAB’s notebook capability Please get the latest ZIP file of the SP-First M-files. |
| Lab#3 AM & FM Signals | 27-Jan to 2-Feb 04 | No FAQ available | Please bring headphones to lab The latest version of CNT can be obtained from CNT EXE. It is a Flash program that runs on Windows only. OLDER version is here: CNT EXE |
| Lab #4
Music Synthesis | 3-9 Feb | Lab-4 FAQ | coscos.m (test file for debugging in the preLab). Song is “Jesu, Joy of Man’s Desiring” Uses two data files in MATLAB binary format: Jesu04.mat contains information about key numbers and types for the entire song. Jesu04short.mat contains only the first 3 measures (useful for debugging). Data is stored in MATLAB structures called Treble and Bass. Download this Jesu04.zip archive. Un-zip to get Jesu04.mat and Jesu04short.mat as well as a copy of the sheet music for Bach’s Jesu, and a WAV file with a piano recording. Help on Structures in MATLAB |
| Lab #5 Digital Images: A/D and D/A | 11-17 Feb | Lab-5 FAQ | Uses three image data files in binary format: lighthouse.png, stinger04.png and stinger04q.png. Download the lab05s04images.zip archive, and un-zip. Some useful information is available in printing-multiple-images. |
| Lab #6 FIR Filtering: Image Interpolation | 18-24 Feb | Lab-6 FAQ | Images are in the data file Lab06s04files.zip file which includes the two images peppers.png and motorcycles.png and their CFA versions in PNG format. It also includes new versions of show_img.m and trusize.m that can display color images. Replace these in the SP-First Toolbox, or download the latest version, v1.09 and update the entire toolbox. Information on color printing in the Library West Commons. CON2DIS and DCONVDEMO should be on the MATLAB path in the ECE-2025 Lab, or in the SP-First Toolbox, or you can get them individually at Educational GUI page **** A new version (v3.06) of DCONVDEMO is available. It has the User Signal capability. |
| Lab #7 Nulling Filters | 25 Feb – 2 Mar | Lab-7 FAQ | Data file is Lab07s04image.zip file which contains a MAT file called Lab07s04image.mat DLTIDEMO should be on the MATLAB path in the ECE-2025 Lab, or you can download it from the GUI page |
| Lab #8 Filter Design: BPF | 15-18 Mar | Lab-7 FAQ is applicable | Data file is Lab8s04sig zip file DLTIDEMO should be on the MATLAB path in the ECE-2025 Lab, or you can download it from the GUI page |
| Lab #9 Touch-Tone Dialing/Detection | 22-25 Mar | Old Lab-8 FAQ | Data file is lab09s04sigs.zip file. It also contains the ttonecut function. |
| Lab #10 Continuous-Time GUIs | 29 Mar – 1 Apr | No FAQ available | CLTIDEMO should be on the MATLAB path in the ECE-2025 Lab, or you can get it from the GUI page CCONVDEMO is on the MATLAB path, or get it from the GUI page FSERIESDEMO is on the MATLAB path, or get it from the GUI page |
| Lab #11 AM Communication System | 5-8 Apr | Old Lab-11 FAQ | Both signal files are in lab11s04.zip lab11s04.mat (811K) contains the “mystery signal” for QAM demodulation. harp2k.mat (935K) contains two “real signals” for testing. |
| Lab #12 (part one) PeZ GUI intro | 12-15 Apr | No FAQ available | No Lab report. Warm-up only, so this must be done entirely in-Lab. Latest PeZ, pezmovie.zip, has the “ray” feature in the Options Menu. In order to run it, unzip, add the pezmovie directory to your MATLABPATH, and then use pezmovie at the MATLAB prompt. |
| Lab #12 (part two) PeZ: 2nd-order IIR | 19-22 Apr | No FAQ available | No Lab report. Warm-up only, so this must be done entirely in-Lab. |
