ECE-2025 Lab Assignments
Fall-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 | 23-26 Aug 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 | 30-Aug to 2-Sept | FAQ | There is new capability in MATLAB v7 for making MS-Word compatible files. We will not require its use during the warm-up, but a description is here. Tutorial movie about MATLAB’s notebook capability in a ZIP file (9.8Mb). Unzip to get the AVI file which should be viewed with Camtasia Player which can be obtained here: camplay.exe in a ZIP file. Please get the latest ZIP file of the SP-First M-files. |
| Lab#3 AM & FM Signals | 7-13 Sept | 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. |
| Lab #4 FM Music Synthesis | 14-20 Sept | No FAQ available | Please bring headphones to lab. Formal Lab Report Required. Worth 150 points. Link to Chowning’s paper |
| Lab #5 Music Synthesis | 21-27 Sept | Lab-5 FAQ | coscos.m (test file for debugging in the preLab). Song is “Fur Elise” Uses two data files in MATLAB binary format: furElise.mat contains information about key numbers and types for the entire song. furEliseShort.mat contains only the first 4 measures (useful for debugging). Data is stored in MATLAB structures called Treble and Bass. Download this furElise.zip archive. Un-zip to get furElise.mat and furEliseShort.mat as well as a copy of the sheet music for Beethoven’s Fur Elise, and a WAV file with a piano recording. Help on Structures in MATLAB |
| Lab #6 Digital Images: A/D and D/A | 28-Sept to 4-Oct 04 | Lab-6 FAQ | coscos.m (test file for debugging in the Warm-up).
