ECE-2025 Lab Assignments
Spring-2005
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.
