BASIC LOGIC GATES FUNCTIONS

AND GATE:

If both inputs are high(1) output is high(1). Else output is low(0).

OR GATE:

If both inputs are low(0) output is low(0). Else output is high(1).

NOT GATE:

Not gate is inverted of input signal.

NAND GATE:

 NAND is complement gate function of AND gate.

NOR GATE:

NOR  is complement gate function of OR gate.

XOR GATE:

If any one of input is high the output is high. Else output is low.

XNOR GATE:

If both inputs is same the output is high. Else output is low.

BUFFER:

It is used for introduce propagation delay in our circuit.
It is used for high fan out.
