1.	Name the 2-input logic gate, whose truth table is given here, If this logic gate is connected to a NOT gate. What will be the output when (i) `A=1, B=1` and (ii) `A=0, B=1`? `\|{:(A,B,"Output"y),(0,0,1),(0,1,1),(1,0,1),(1,1,0):}:\|` `\|{:(A,B,"Out put"y,"Output of Not gate"),(1,1,0,1),(0,1,1,0):}\|`
Answer» For the output y, the Boolean expression applicable is `y=bar(A.B)` , Hence, the table is of NAND gate. When output of NAND gate is connected to input of NOT gate, the output of NOT gate `=bar(bar(A.B))=A.B` (i.e. AND gate).
