Combination of fundamental logic gates:

Gate 5:-  NAND

Description: This gate is fundamental of any operation where output is complement of product of all binary inputs.

Output = (Input1 * Input2 …….. * Input N)’

Where, outputs and inputs are all in binary values ’1’ or ’0’

Gate 6:- NOR

Description:  This gate is fundamental of any operation where output is complement of addition of all binary inputs.

Output = (Input1 + Input2 …….. + Input N)’

Where, outputs and inputs are all in binary values ’1’ or ’0’

Gate 7:- Exclusive-NOR (XNOR)

Description:  This gate is fundamental of any operation where output is low only when two binary inputs are different.

Output = (Input1)’*(Input2)’ +  (Input1) * (Input2)

Where, outputs and inputs are all in binary values ’1’ or ’0’
