            Course Information and Bibliography (pdf)
            Course Syllabus (pdf)

           Resources:

                SignalShow: A free software program written in Java by former undergraduate student Juliet Bernstein for illustrating the concepts in this course.
                    Available for the three most common personal computer platforms (Windows, Macintosh OSX, and Linux). 
                    The compiled JAVA programs are available at:  http://homes.cs.washington.edu/~juliet/photography/SignalShow.jar
                    The source code is available at: (Dropbox link): https://www.dropbox.com/sh/h3c07v15kf1ptao/PQ1_7n8nEa

                    Videos are posted on YouTube  that illustrate the use and features of the program.

                Signals: A DOS program for demonstrating Fourier transforms of one-dimensional functions; available as a zipped file from the CIS FTP site:
                     http://www.cis.rit.edu/people/faculty/easton/signals/signals.zip
                            The program  runs quite well in "DOSBox," which is available for many platforms (Windows, Mac OSX, Linux)  from http://www.dosbox.com/
                            The user manual for the DOS version of SIGNALS is available online at:  http://www.cis.rit.edu/resources/software/sig_manual/
                             (see me for help with installation, if needed)

                Audacity: http://audacity.sourceforge.net/   (for generating audio waveforms and recording/editing sound files, includes FFT analysis

                Spectrum Lab: (audio spectrum analyzer): http://www.qsl.net/dl4yhf/spectra1.html#download

               Paul Romanczyk's Mathematica  tool for adding sinusoidal waves  --- link to Mathematica Player download    
               Online tool to invert matrix (up to 9 × 9)  

    Text:  
         Fourier Methods in Imaging, Roger L. Easton, Jr., John Wiley and Sons, 2010, available from the RIT Bookstore and the other usual suspects.  
              (I  have some old bound copies of course notes to give away for free, but note that there are some minor differences between the old and new versions)
