NOT gate



NOT Gate

NOT gate - This gate inverts the input and places the inverted value at the output, If you apply a 1 at the input the output will be 0 which is the reverse of 1, and vice versa.

AND gate

AND Gate

AND Gate - This gate ANDs the two inputs A and B, The Output is high only if A AND B both are high. There may be an AND gate with many inputs, only if all inputs are high the output will be high.

AND Gate Tutorial



OR gate

OR Gate

OR gate - This gate ORs the two inputs A and B, The Output is high if either A OR B is high. There may be a OR gate with many inputs, if one or more inputs are high then the output will be high.

XOR gate

XOR  Gate

XOR gate - This gate XORs the two inputs A and B, The Output is high only if either A or B is high, output goes low if both inputs are high or low. There may be a XOR gate with many inputs that may work as XOR or Parity Gates.
