Dr. Jeffs teaches a wide variety of graduate and undergraduate courses in the areas of signals and systems, and electronic circuits. At the graduate level his regular lectures include Digital Image Processing (ECEn 678), Advanced Digital Signal Processing (ECEn 777), and Stochastic Processes (ECEn 670). Undergraduate offerings include Introduction to Digital Signal Processing (ECEn 487), Real-time DSP laboratory (ECEn 487 Lab), Probability theory (ECEn 370), Software Radio Senior Project (ECEn 490), Signals and Systems (ECEn 380), Introduction to Circuits (ECEn 212), and Electronic Circuits and Devices (ECEn 313).

The following list itemizes some of the curriculum innovations and new courses developed and introduced by Dr. Jeffs.

ECEn 487, Discrete-Time Signal Processing lecture and Real-Time Digital Signal Processing Laboratory. The lecture course was revised and moved to the undergraduate level by Dr. Jeffs. This permitted much more advanced offerings at the graduate level. The associated real-time DSP lab, developed by Dr. Jeffs, uses the TMS320C6701 floating point signal processor evaluation module. Students develop code for filters, a spectrum analyzer, acoustic direction finder, and adaptive noise canceller.

ECEn 490, Software Radio Senior Project. In this lab course, teams of upper division students (four per team) design a complete operational DSP-based digital communications receiver in a competitive environment. The 924 MHz QPSK receiver is implemented in real-time DSP code on a Texas Instruments TMS320C6701 floating point evaluation board. Students must design and build the antenna, radio frequency front-end circuits, and develop code for the digital demodulation. Teams compete based on lowest transmit power required for a specified bit error rate at a fixed distance. Winning teams receive a significant cash award from corporate sponsors.

3	ECEn 212 lab, Circuits Laboratory. This course is based on a semester-long major project where the students design and build a complete stereo audio amplifier and speaker system, and in the process apply all of the major circuits principles taught in class.

4	ECEn 380 Signals and systems. Dr. Jeffs led the effort in 1991 to have this course on linear systems and transforms expanded and moved from the graduate level to be taught at the Junior level. The current course syllabus was developed and first taught by Dr. Jeffs.

5	ECEn 316, Signals and Systems Laboratory. This companion to ECEn 380 included op-amp and DSP-based experiments to study principles of both analog and digital linear systems.

6	ECEn 687, Advanced Digital Signal Processing. Includes topics of statistically optimal signal processing, array processing, adaptive filtering, parametric spectral analysis, etc.

7	ECEn 619, Advanced Digital Image Processing. Includes in depth study of iterative and regularized methods for image restoration and medical image reconstruction. The ill-posed inverse problem is analyzed.
