As we learnt in 

OR gate -

Relation between input and output

    Y= A+B

- wherein

A and B are input

Y is out put

 

 

AND Gate -

Y= Acdot B

- wherein

A and B are input

Y is out put

 

 

NOT gate -

Y=ar{A}

- wherein

A is  input

Y is out put

 

 

NAND gate -

NOT + AND gate

- wherein

Y= overline{Acdot B}
