What is Logic Gates?

The Logic Gates are circuits made up of transistors, diodes, and resistors. The Logic gates process one or more input signals in a logical fashion. Depending on the voltage or input value, the logic gate will either output a value of '1' for ON or a value of '0' for OFF. Logic Gates allow simplification of circuit operation.

Logic states

 True 

False

1

0

High

Low

+Vs

0V

On

Off

The Logic gates process signals which represent true or false. Usually the positive supply voltage +V represent true and 0V represents false. Other conditions which are used for the true and false states are shown in the table.

A truth table is a good way to show the function of the logic gate. It shows the output states for each possible combination of input states. The symbols 0 (false) and 1 (true) are typically used in truth tables.
