The most interesting subject of electronics is Digital Electronics. It shows us that everything from human voice to signals from space satellites can be
expressed in terms of 1 and 0. This module of Simtel illustrates user the basic concepts of digital electronics. More emphasis is given on practical
constraints of digital circuits. Simtel Digital Electronics contains simulations and animations on Boolean algebra, Logic gates, and Sequential circuits
which explains their working and concepts in a manner that is clearer, interesting, and easier to understand.
