1] Logic Friday LogicFriday is a free logic gate simulator software that comes with great features. In this software, you can create Truth Tables, Logic Equations, and Logic Gate Diagrams.

For example, an AND gate outputs 1 only if both inputs are 1, while an OR gate outputs 1 if either input is 1. There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR.
