Logic gates are the bricks and mortar of digital electronics, ... depends on the two inputs according to the truth table at the right. The AND gate has a “1” output only when both A and B are 1.

A truth table basically displays outputs for all possible combinations of input values to a logic gate or circuit. It either shows True and False values or 0 and 1 values.

Learn about digital data and how computers understand it, including binary, denary, hexadecimal numbers, units of data, character sets and logic gates.

In this software, you can create Truth Tables, Logic Equations, and Logic Gate Diagrams. Go to “ File > New ” to create a new project. You can add 2, 3, or 4 input logic gates to your project.
