Aims/Objectives
To introduce digital electronics with emphasis on practical design techniques for logic circuits, analysis of static and dynamic behavior of logic circuits and optimized circuit implementation with its principles in Boolean algebra. To introduce the design of combinational and sequential logic circuits with gate level implementation. To teach how simple combinational and sequential modules are used to build complete systems, reflecting real-world digital design.
