Course and Laboratory Development
ENES101: Developed a set of course notes on engineering graphics for use as an addendum to the textbook. Also, contributed a set of engineering related programming exercises and projects in ``Microsoft QBasic: An Introduction to Structured Programming for Engineering, Mathematics, and the Sciences, David I. Schneider, MacMillan, 1991 which were used in the course.
EE331: Revised the contents of the course and introduced design projects to satisfy ABET requirements.
EE341 and EE342: revised the contents of the courses and introduced more design projects into the courses. Two new laboratory exercises on diode circuits and BJT amplifiers were developed in EE341. Also, the software packages PSpice, Mathcad, and MATLAB were used in the two courses.
EE342: Special research projects involving the design and simulation of analog electronic circuits (amplifiers, current mirrors), digital circuits (multivibrators), signal processing systems (filters, hearing aids), and biological systems (neural-type cell circuits and hair-cell type circuits) were assigned. This was done to introduce the students to some real-life applications of electronic circuits studied in class, as well as to prepare them better for the senior design project course. The projects required doing a literature survey, learning new concepts, implementing (with hardware and/or software) the design, testing/debugging, and writing a report.
EE322: revised the course contents and introduced Matlab as a high level programming language and a tool for learning difficult signal analysis concepts. Matlab was extensively used in the lab and homework assignments for solving signals and systems problems. A set of 8 new laboratory exercises were developed and coordinated with the course material to ensure that laboratories have maximal benefit. In each lab the objectives and the background knowledge needed to perform the labs were outlined for the students.
