This video is an introduction into Binary Addition. It discusses the concept of binary addition and it discusses how we can create a half adder and a full adder using logic gates (XOR, AND and OR). The video follows on to another video on 4-bit addition, which cascades full adders together to create the 4-bit adder circuit. This video is part of an introductory module on Digital Electronics that takes place at Dublin City University (DCU), Ireland. See: www.eeng.dcu.ie/~molloyd/EE223/
