Logic gates are building blocks of digital circuits. They are electronic circuits that perform logical operations on one or more inputs to produce a single output signal.
There are several types of logic gates, including AND gates, OR gates, NOT gates, NAND gates, NOR gates, and XOR gates, each of which performs a specific logical function.
AND gates: An AND gate has two or more inputs and produces an output that is high only when all of its inputs are high.
OR gates: An OR gate has two or more inputs and produces an output that is high when any one of its inputs is high.
NOT gates: A NOT gate, also known as an inverter, has a single input and produces an output that is the opposite of its input.
NAND gates: A NAND gate is an AND gate followed by a NOT gate. It produces an output that is the opposite of an AND gate.
NOR gates: A NOR gate is an OR gate followed by a NOT gate. It produces an output that is the opposite of an OR gate.
XOR gates: An XOR gate, also known as an exclusive OR gate, has two inputs and produces an output that is high only when one of its inputs is high, but not both.
