=== What You Will Learn ===
In this tutorial you will use generic inverter gates and two-input NAND gates to build a three-input AND circuit. You will learn how to define digital inputs and outputs and use [[RF.Spice]]'s live digital timing diagrams. It is assumed that by this time you have already completed the first few analog tutorial lessons and are comfortable with navigating the [[RF.Spice A/D]] Workshop.
