I'm an engineer and part-time lecturer at the University of Alabama in Huntsville.  This channel is a collection of teaching resources I've developed over the years that I make available for my students.  The content is focused in the areas of signals and systems, digital communications, random processes, linear algebra, and Matlab.
All my videos and a large collection of additional content found at my website: http://adampanagos.org
