6 EE201: Digital Circuits and Systems Introduction page 6 of 7 Advice: Attend lectures o The lecturer presents the most important material o Your presence is strongly recommended o Take notes and read them at home o Keep them and review them later on Attend tutorials o Read lecture notes and textbooks before tutorials o Prepare questions and ask them o Your presence is strongly recommended as you can clarify some aspects not fully understood Do not miss any practical o Practicals are compulsory o You have an opportunity to exercise theoretical knowledge Buy the laboratory manual o You need it during the lab sessions o You can get it from Hodges & Figgis bookshop (campus) o You also need a lab notebook

7 EE201: Digital Circuits and Systems Introduction page 7 of 7 Borrow books from the library o Read them! o Take notes o Exercise Ask questions o Lecturer after the lectures o Tutor during the tutorial o Demonstrators during lab sessions Work on your own o Solve problems o Save solutions o Devise your own problems o Try to solve them o Practice as much as you can Prior knowledge o Binary Arithmetic: 2 s comp Add/Sub o Combinational Logic: logic gates, KM o Sequential Logic: flip-flops, shift registers, counters
