Digital Logic Tutorial

• NAND The logical basis of all computing
• RS Flip Flop How computers learn and remember
• Binary and Decimal Numbers
• Binary Addition Circuit
• Binary Full Adder

This series makes use of a program written by Andreas Tetzl of tetzl.de that makes the NAND gate, and the things we build from it, come alive on your screen. It is called LogicSim and it is a digital logic simulator that can work from a web page. If we did not have LogicSim, we could only tell you how it all works and could not show you. To use LogicSim, you must have Java^tm from Sun Micro systems. You can check if you have Java on their web page at java.com. Look for the "Do I have Java?" link.
