Question

# The combinations of the NAND gates shown hereunder are equivalent to

A
an OR gate and an AND gate respectively
B
an AND gate and a NOT gate respectively
C
an AND gate and OR gate respectively
D
an OR gate and an NOT gate respectively

Solution

## The correct option is B an OR gate and an AND gate respectivelyTruth tables for logic (1) and (2) are shown below:Input       Output$$(0,0)$$$$0$$$$(1,0)$$$$1$$$$(0,1)$$$$1$$$$(1,1)$$$$1$$Input Output$$(0,0)$$$$0$$$$(1,0)$$           $$0$$$$(0,1)$$$$0$$$$(1,1)$$$$1$$The truth tables are equivalent to OR and AND gate.Physics
