It output doesn’t depends upon on the past inputs. The output of combinational circuit is dependents upon the present inputs only. The combinational circuit is the combination of logic gates like AND, OR, NOT & EX-OR etc. At any instant of time the output of combination circuit is depends upon the present input.It is different type’s circuit such as Adder, Subtractor, Encoder, Decoder, Multiplexer, and De-multiplexer.Ĭombinational circuit has some characteristic which is given below It does not depend on past and future inputs. The output of combinational circuit is depends on present inputs only. In other word, the different types of logic gate like AND, OR, NOT & EX-OR etc gate are combined is known as a combinational logic circuit. The combinational circuit is digital logic circuits that contain different types of logic gates. input=f (output) what is a combinational circuit
In mathematical term, output is the function of input, i.e. The combinational circuit is to perform Boolean algebra.
Half adder truth table k map full#
Some examples of combinational circuit is half adder, full adder, multiplexer, demultiplexer, codes converter encoder and decoder. The combinational circuit is made by NAND, NOR and NOT logic gates, and the logic gates are made up electronics components. It means the present output of the circuit is not depending on the previous input. The combinational circuit is the combination of gates, whose perform the various type of digital operation.
