Logic Gates

Logic gates are small digital electronic devices that perform a Boolean function with two inputs and provide an output. The data are binary ones. Logical 1 is true or high, and logical 0 falls to false or low. Based on the logical gate, the logical operation differs, and the output varies. Each logic gate follows a truth table that gives the possible combinations of input and the respective obtained output.

The operation of every single logic gate can be easily understood and is similar to addition and multiplication that we already know in ordinary mathematics. A logic gate is identical to a light switch such that it is on when the output is one else off if the production is 0. Various electronic devices are given a form with logic gates, and they get used along with diodes, transistors, and relays. Some of the most widely used transistor families like TTL 7400 series from Texas Instruments and CMOS 4000 series got fabricated with the aid of small-scale logic gates.
