Logic gates are at the basis of **digital circuits**. They carry out the basic functions of **Boolean Algebra** using digits in **binary code**.

This original theory, developed by George Boole in the 1830's, is at the heart of all current computer systems, which can function only with digital inputs, in binary code.

**Combinational Logic** only deals with logical functions in which the output depends solely on the inputs. This differs from **Sequential Logic**, in which the outputs also depend on inputs, but also on previous outputs ("memory" effect).

This animation only permits simulations using **combinational **Logic functions. It may not function using **sequential **logic. Nevertheless it should work for regular Flip-flop and latch circuits (like SR latch).
