Basic gates Basic Logic Gates. All digital systems can be constructed by only three basic logic gates. These basic gates are called the AND gate, the OR gate, and the NOT gate. Some textbooks also include the NAND gate, the NOR gate and the EOR gate as the members of the family of basic logic gates. Types(basic) 1.AND gate 2.OR gate 3.not gate

1. AND gate: The AND gate is a basic digital logic gate that implements logical conjunction - it behaves according to the truth table to the right. A HIGH output results only if all the inputs to the AND gate are HIGH. If none or not all inputs to the AND gate are HIGH, a LOW output results INPUT	       OUTPUT A	B	A AND B 0	0	0 0	1	0 1	0	0 1	1	1

2.OR gate:

INPUT	       OUTPUT A	B	A OR B 0	0	0 0	1	1 1	0	1 1	1	1

3.NOT gate: A NOT gate (also often called Inverter) is a logic gate. Each NOT gate has only one input signal. Logically with NOT gates, the input and the output swap, so if you input 1 it outputs as 0; likewise if you input 0 it outputs as 1.
