LE242: Digital Circuit Design


Course Information

Description: This course introduces the design and implemenatation of digital circuits. Topics include number representations, codes, Boolean algebra, logic gates, combinational and sequential circuit design (both synchronous and asynchronous). The real implementations begin with basic gates and progress to Programmable Logic Devices (PLD).
