NAND gate

NAND gate :- It is complement of AND gate. It produces low signal output iff all the input signals are high. It has n input and 1 output.
For a 2-input NAND gate,if A and B are the input signal then output signal Y can be represented as  Y=\(\overline{A.B}\)​ ​​.
This gate is represented as
