ECE-2025 Lab Assignments
Fall-2001
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
. It should work in version 3.0 or later, but it works best with version 4.
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.
*** TEMPORARY FIX for old m-files.
Please get the ZIP file that has updates for zvect.m, zcat.m, etc.
Un-zip and put these files at the BEGINNING of your MATLAB path.
Labs
| Description | Lab Dates | FAQ** | Supporting Material & Links |
| Lab#1 | 27-31 Aug-01 | FAQ | Getting Started with MATLAB (1.1 Mb PDF file from Mathworks) Little Bits of MATLAB (Old MATLAB tutorial) Another MATLAB Tutorial (written by Prof. Heck) |
| Lab#2 | 4-10 Sept-01 | FAQ | Uses one supporting file called DF_gen.p. Download DF_gen.p in binary, or in the DF_gen.zip archive Un-zip to get DF_gen.p and then put this file in your current directory. ***11-Sept, DF_gen.p created in MATLAB ver 6 was removed; the version above was created by ver 5.2 of MATLAB. |
| Lab#3 | 11-18 Sept-01 | No FAQ available | The beatcon.m function is in the DSP-First toolbox. |
Lab #4 Music Synthesis | 19-25 Sept-01 | Lab-4 FAQ | coscos.m (test file for debugging in the warm-up). Song is “Fugue #2 for the Well-Tempered Clavier” Here you can find a MIDI example of the Bach Fugue #2. Uses two data files in MATLAB binary format: bach_fugue.mat contains information about key numbers and durations for the entire song. bach_fugue_short.mat contains only the first 3 measures (useful for debugging). Data is stored in a MATLAB structure called theVoices. Download this bach_fugue.zip archive. Un-zip to get bach_fugue.mat and bach_fugue_short.mat Sheet Music for Fugue #2 for the Well-Tempered Clavier How to Plot the Spectrogram as an Image M-file to plot the Spectrogram. Make sure that you get the new spectgr.m also from the M-files link. Help on Structures in MATLAB |
Lab #5 Digital Images: A/D and D/A | 26-Sept to 2-Oct | Lab-5 FAQ | Uses one image data file in MATLAB binary format: lighthouse.mat Download this lab05images.zip archive. Un-zip to get lighthouse.mat Some useful information is available in printing-multiple-images. |
Lab #6 FIR Filtering of Digital Images | 3-Oct to 9-Oct | Lab-6 FAQ | Download this ZIP file for Con2Dis (v0.97): CON2DIS illustrates aliasing and reconstruction for sampling. It has BEEN TESTED on v5.3 and v6 of MATLAB for Windows & Linux. DCONVDEMO should be on the MATLAB path in the VL-252 Lab |
