Explanation

There are several fundamental logic gates. Here's a list explaining them all and with tools to test them out!

AND Gate

The AND gate takes two or more inputs and produces an output that is high (1) only when all inputs are high.
The output (Y) of an AND gate can be calculated using the Boolean expression:
