DIGITAL ELECTRONICS

This subject, as the name suggests, deals with the electronics ciruits, their working, designing, logic etc. This subject is very simple and much faster to understand to those who were in Vocational science. This doesn't mean other will not be able to grasp, they will be able to, but, will take longer time, comparatively. This subject requires constant practise. It includes Number conversions, Boolean algebra, Logic gates, Flip-Flops etc.
