ENEE244 Digital Logic Design

Course Description 

This course covers switching algebra and its use in design with logic gates, flip-flops, registers and counters, and the analysis of these networks. Also covered are Karnaugh map simplification of gate networks, design and analysis of synchronous sequential systems, implementation with PLA's, multiplexers, decoders, encoders, binary arithmetic units such as adders and subtractors, conversions between decimal and arbitrary radix numbers, especially octal, hexadecimal, and binary representations, radix and diminished radix arithmetic, and character codes.
