Fundamental Logic Gates with Truth Table:-
A circuit that performs a specific logic operation (AND, OR) is called a logic
The inverter (NOT circuit) performs the operation called inversion or complementation. The NOT operation changes one logic level to the opposite logic level. When the input is Low, the output is high. When the input is high, the output is low. The inverter changes one logic level to the opposite level. In terms of bits, it
changes a 1 to a 0 and 0 to 1.
THE AND GATE:-
An AND gate can have two or more inputs and performs what is known as multiplication. The output of AND gate is high when all inputs are high otherwise all outputs are low. An AND gate produces a HIGH output only when all of the inputs are HIGH. When any of the inputs are LOW, the output is LOW. Therefore, the basic purpose of AND gate is to determine when certain conditions are simultaneously true, as indicated by High levels on all of its inputs, and
produces a High on its output.
THE OR GATE:-
OR gate can have two or more inputs and performs what is known as a logical addition. The output of OR gate is Low when all inputs are low, otherwise, all outputs are high. An OR gate produces a High on the output when any of the inputs is High. The output is Low only when all of the inputs are Low. Therefore, an OR gate determines when one or more of its inputs are High and produces a High on its output.
