ECE Department. University of Florida. Introduction. There are many ways to implement a digital function, but each approach may have different tradeoffs. As a digital designer, you need to consider these tradeoffs when meeting design requirements. Prof. Taeweon Suh. Computer Science & Engineering. Korea University. COSE221, COMP211 Logic Design.
