    Teaching

    EE 232
    Digital Electronics

    An introduction to digital logic including combinational and sequential logic devices and circuits. Covers the range from the fundamentals of Boolean algebra and the binary number systems to combinational and sequential circuit functional blocks such as adders, multiplexers, counters and state machines. Some coverage is also given to electronic characteristics of real logic devices and field programmable gate arrays (FPGA).

    EE 331
    Microprocessor Hardware and Software

    Covers the architecture and operation of microprocessors and memory devices, linking together of logic devices. The assembler language is introduced to program low level functionality of microprocessors.

    http://www.engr.usask.ca/classes/EE/331/
    EE 395
    Electrical Engineering Design

    Covers the "top down" approach applied to engineering design. The students will exercise the approach by designing, building and testing one or two projects. The course also includes aspects of manufacturing engineering and, project organization and control.
