The purpose of Electrical Engineering Study Guides (EEguides) is to help engineering students, or anyone else that is interested in electrical engineering concepts, understand common electrical engineering principals. At first, these documents will focus on signal processing and communications, but they may be expanded later. When the project is finished, the documents should be able to be put together to form a textbook-like document that will be free (GNU Free Documentation License) to anybody.
Each of the documents will feature the idea of "prerequisites" so that any reader will get an idea of what they will encounter inside the document. Each document will also feature examples that the reader can execute on the free software Octave (compiled with the FFTW library) and view with Gnuplot.
