=== What You Will Learn ===
In this tutorial you will use generic inverter gates and two-input NAND gates to build two-input and three-input AND circuits. build a three-input And function out of a three-input Nand gate (7410) and an Inverter (7404). You will learn how to define digital inputs and outputs and use [[RF.Spice]]'s live digital timing diagrams. The digital circuit of this lesson is shown in the figure below:
