Digital Circuits & Logic Design
Subject Overview
Digital Circuits & Logic Design covers number systems and logic gates, Boolean algebra and combinational circuits (adders/subtractors), multiplexers/decoders and sequential circuits (flip-flops), and counter design using timers and up-down/MOD-N counters. A 4-credit core theory paper.
