Digital Logic Tutorial

NAND The logical basis of all computing
- And how they can make all the other gates
RS Flip Flop How computers learn and remember
- although the D Flip Flop is a bit closer to a bit.
Binary and Decimal Numbers Count like a computer
Binary Addition Circuit NANDs can Add! A little bit anyway.
- Binary Full Adder but NAND adders can really add.
A 2 bit to 4 line active low decoder Stepping through a sequence.

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.
