Combinational circuits


Combinatorial Circuits are circuits which can be considered to have the following generic structure.

Whenever the same set of inputs is fed in to a combinatorial circuit, the same outputs will be generated. Such circuits are said to be stateless. Some simple combinational logic elements that we have seen in previous sections are "Gates".

Below figure shows the basic gates that are used to build a combinational circuit.
